Misfire Case Study (1999 Honda Accord)

[@haunebu2360]

I have this car. I’ve learned a lot about it thanks to this video. ! My misfire was the distributor rotor, or (whatever it’s called!). I replaced that and the cap. And it fixed my problem! As you can tell I’m not a mechanic!

[@kalanirobb54]

This dude has a real grip on modern engine management,you can see that with a true grasp on the basic fundamental principles .you can use logic and the process of elimination to save time and cut to the core of automotive issues. Thank you sir! Good day!

[@jeffersonvalleyperformance351]

EXACTLY

[@VintageCybin]

This video is absolutely gold for me. I have a very similar misfire going on with my Honda im going attempt to identify using low tech strategies. Thank you for such a easy to understand, funny and knowledgeable video. Ill post a update

[@nef003]

I have the same issue. I figured it was the Injector by unplugging it from the back; the car showed no signs of rpm change. Great work. I'll go ahead and replace the injector :)

[@Anthony-ir8dy]

Your vids never get old, even the old ones. A lot of good auto channels out there, yours is the funnest.

[@bruceLi2011]

at 11:40, the single cylinder misfire triggering multi-cylinder misfire code is very valuable. It gave me a hint to try to replace a ignition coil on a cylinder i found bad when the code P1399 was multi-cylinder random misfire. It fixed the problem eliminating check engine light and TCS light on my 2000 TL. Thanks so much for posting this video.

[@VonSpud]

That was great 👌 I'm doing some pro-bono work on my wifes cousins 1999 Honda Accord with same issue. Weekend mechanic here using a 3160RS OBD2 analyzer that is telling me there's eight issues and three of them are missfire related (random). 3 plugs were burnt looking and one was dark. All 4 had .060 gap instead of. 039-.043. I swapped out old ones for new NGK plugs. Starts nice, idles rough... revs ok...sounds like it wants to die on rev down. Stalls easy. (Standard trans) Going to do those drop and compression tests next. Thanks !

[@steveharrison8995]

Just watchd your video on the Honda injector problem, You come across as knowledgable and genuine, so thank yhou

[@nomercy0401]

man you have no idea how much this video help me understand what was wrong with my accord thank you brother

[@crazytestpilot9434]

You can sure tell the difference with these videos when a real pro is doing the talking. Thanks for a great vid.

[@the_retired_mechanic]

Superb. I so enjoy it when these things don't go to plan (just like the real world Paul). But you got there in the end. True professional once more. And i learn some thing new at the same time.

[@ScannerDanner]

This video didn't show the struggle I had with the fuel system. I tried and tried so many different ways to get my psi gauge installed and I failed. Thanks so much!

[@vessellsbuzz]

Paul, I enjoy all your videos. Your live diagnostics videos the best. You can have a dead misfire like that with a intake runner gasket just leaking on that cylinder. You will not hear it and it will not show up in fuel trims. Poor a gallon of water on the intake and see if you hear it being sucked into the engine and you will see steam come out the exhaust. Typically the KV line will be higher on the cylinder with the intake runner leak. Thank you so much for all the great videos.

[@ScannerDanner]

Absolutely my friend, and I love the water test too. I actually have a video on that here on KZbin on a Dodge Neon with a misfire. Intake Runner Vacuum leak (water test) And I did check for this on this car, just forgot to mention it. Sorry about that.

[@NullH3ad]

This shows awesome perspective of what a technician faces in the field ... great video. I face this at work often. I recently picked up a Snap-On Verus and am working on my scope skills, but let me tell you. It is very difficult to do what you did without a scope. I would have sold the guy an injector based on the evidence, assuming all your parts are good, the process of elimination proves that it's an injector issue. Having the right tools for the job really makes the differences. Knowing how to use them, is what makes you a good tech.

[@ScannerDanner]

Thanks Bro. Sorry I didn't go over the compression waveforms in this video. I was so drained by the end of it.

[@alexhickey5633]

I have one of these from 99 with the f18b2 vtec engine in it. F series engines are absolutely bulletproof

[@coldfusion112002]

If only you could find the person who did this hack job with the spacers and anti-fowler and beat them. That's a new one for me. Ive never seen something so ridiculous as that. That person should never work on a car again in their life. My dad gave me a good bit of advice that went something like this.... "If you're experiencing new issues with something that are similar to the original problem, check the work that was done last and it's most likely the problem." Good video. I learned some things from it.

[@carpo719]

This is the exact problem I have with my Honda and I haven't been able to identify any solution, I sure hope by the end of this I have found one!

[@ScannerDanner]

It was a bad injector

[@datchulo1085]

Thank you sooooo much for posting this video, because of you I was able to fix my car. I sure wish I. Had you as a professor in Lincoln tech

[@jamiesimpson1786]

Hi Paul. Sometimes you can't see the forest for the trees. It happens to all of us. I diagnosed a car with clogged injectors a month or so back using what I learned from you by testing secondary waveforms. Problem is there are so many ways to test, and so many different makes & models that doing this sort of work you are challenged everyday. But then, this is why we enjoy doing it. If it was easy every one would do it and get it right first time. As we all know this is not the case. Keep up the good work.

[@ScannerDanner]

For sure man, I definitely had some tunnel vision on this car. Thanks!

[@AamirZ]

Another fantastic video Paul! Really enjoyed watching this and love these videos when you have problems like this. Really good to watch and we all learn something too!

[@aqilbintory2308]

So much to learn from this... I am still a Carookie !Thanks.. uploader

[@raydavies6236]

"massive misfire" Starts it up, runs better than a new Chrysler.

[@btbird57]

Should have said Ford lol

[@declanosbourne62]

These guys are awesome..they are really a trusted mechanic..good work man..it pays to do a good work so you can get recommend.

[@blackericdenice]

Dude, I thought you was crazy for pulling them wires off the distributor like that. Keep a test light near by. I learn something from you every time I stop by.

[@8power0]

I would be surprised if this is not a low fuel pressure problem, possibly a bad fuel pressure regulator great video and thanks.

[@reyhb1]

I love these shop call videos, good job ScannerDanner

[@marianajaldin2757]

Deserves so much more views. Pure school.

[@ScannerDanner]

Thank you! Glad you found me

[@RobbyWorld1]

My 97' Odyssey 4 cyl. started missing. The plug wells were filling with oil from leaking gaskets. Sopped it out with paper towels and long surgical forceps. That was it. Runs perfect. Easy to do when needed. FREE.

[@leoc245]

Great instructional video. I'm not a car/mechanic guy by any means. I own a 1999 Honda Accord and I'm now willing to get down an dirty to learn about how to fix stuff. Keep up the good work. You're probably the best technician I've seen online. I wish I knew someone like you. I could really learn a lot. Thank you.

[@villamarinajc4836]

I had a hard time not seeing you use an ignition scope and a vacuum Guage from the start. The cranking compressing test was good. Another way to check for injector flow could have been to look inside the cylinder. With the intake valve open and activate the injector. Activating the pump if needed but residual pressure could have done it. If it was a restricted injector, activating the injector manually while idling could have given it enough fuel to fire and sometimes clears out the obstruction. A four gas analyzer would have gone a long way. I know you said you wanted to keep it low tech but that was agonizing. Glad I watched it. Thanks for doing what you do.

[@GSRThree]

Hilarious I love it when stuff just keeps failing. Shooting the boot out was great. I think that's a compression tester adapter that you found in the number two hole I have one that looks just like it.

[@PhattyMo]

LOL!! spacers and crap on the plug. OMG. I'm dying.

[@guayaco-dm3vu]

Can't believe people actually do crap work like that and sleep well.. Another job well done Paul, Thanks for sharing your experience

[@billsmith2212]

They don't care , as long as the car " runs" to sell at auction . Some wiseguy would SWEAR it was running PERFECT . They would put in parts from a BATHTUB if they thought it would work . They don't have a concept of what a lean misfire us . They they think it's like changing bulbs in a string of Christmas lights . Just keep putting in parts - ANY - parts , till it works . A plug is a plug - as long as it fires . We don't need no stinkin' heat range . Oh crap - the piston hit that LONG plug - it came out of a LAWNMOWER ! IDIOTS ! Shovel operator at horse stable !

[@teristoledo]

just watched it again after 8 years. the difference from then to now is obvious... :) :)

[@ScannerDanner]

For sure my friend

[@mike-yp1uk]

I've found that taking an old spark plug and wizo wheel 4 stripes makes a great thread chaser fill the sliced parts with grease to capture aluminum debris. This works with any bolt. Clean out cylinder head bolts into the block with an old bolt. Works on subframe bolts ECT... 3 or four slices up the side of the old bolt.

[@janvanmaanen7445]

WOW! This is an excellent video. Your the man I learn a lot

[@ChrisWilson5006]

Was it just me who thought the compression tester was slow to ramp up? I had visions of VVTi issues. Another great video Paul!

[@jamesbasnar8498]

GREAT VIDEO PAUL, LEARN SO MUCH SO MUCH STILL TO LEARN KEEPEM COMING

[@keinoclarke9317]

You're the man Scanner Dan!

[@wyzeprobe4114]

Hey, nice to see you are human. We all suffer from brain fog at times when doing diagnosis. Sometimes when chasing my tail, i have found a dinner break does wonders.

[@ScannerDanner]

+WyzeProbe i certainly am. Hey are you the designer of the WyzeProbe? I've used it in many of my videos. Great tool man thanks!

[@wyzeprobe4114]

+ScannerDanner Yes I am the WyzeProbe designer. Thanks so much for your kind words. Can't wait to see more of your videos, they are a fantastic resource!

[@Big_LosF]

bro this is a bad ass video. really like the attention to the detail of everything u looked at. got ur self a subscriber.

[@ScannerDanner]

thanks Carlos!

[@jarinwilson9539]

Watching closely, it appears the P/S pump bearing might be going out(notice it wobbling a lot) within the first minute of this case study...or I'm just 'seeing' things. It may just be the camera angle. Honda clear flood mode-good luck, haha. Honda loves to blind rivet their TPS to their throttle bodies, sort of annoying. It is pretty well known in this industry that Autolite's are for Fords, come on now people. This is comical yet ridiculous. Another common sense straight to the point video, I love it Paul.

[@toyotatechMDT]

That was very funny when the 'humble' message came up! I was thinking the video was a little long for a bad plug! Great video.

[@luissagastume4984]

i recently bought your book, is a really nice and well explain book.. i just ran in a Honda Odyssey Missfire Cyl #5 that comes along with P0300 random misfire as well... i do all kind of test, spark, fuel injector delivery , swaps coils, swaps injectors, compression allacross, injector pulse, coil primary signal. intake gasket leak.. with no LUCK... i star scratching my head sooo badly . i was frustrated and i think what else can i do... and i dicied to remove the valve cover to see is there is valve calibration AND I WAS RIGHT!!! ONE OF THE 2 INTAKE VALVE WAS LITTLE TIGHT THAT CAUSE ME THAT MISFIRE... CALIBRATION ALLACROSS SOLVED MY HEADACHE.. how i recognice i tight valve Compression good and i ran leak down test and fine too... Thanks for the Book Danner

[@ScannerDanner]

+Luis Sagastume only a running compression test would reveal that or a picoscope and pressure transducer in the cyliner. Thanks!

[@badmofo350]

Great videos man! I wish all mechanics were as thorough as you and Eric O. If only i could get one of you to diagnose my intermittent loss of power to passenger power window motor issue. I read something about a multiplexer that could be the issue.

[@ScannerDanner]

Eric is a great guy to learn from too man. No doubt.

[@steveguest8028]

Love this video Paul,I thought it was just me that had grief with vehicles lol,must admit it looked like an HT problem though especially when you found that bodged up spark plug,I can't believe someone actually did that lol

[@SensWarrior6]

Favorite bit: 22:06 - 22:08 Lol great video; Very helpful and insightful.

[@stevenb320]

I got a 2000 honda accord 2.3l vtec engine code misfire cylinder 1, new plugs wires cap rotor ignition coil Engine code P1399 also shows Engine light flashes Egr cleaned No vacuum leak Throttle position sensor new Idle air sensor new Throttle body cleaned Has strong spark on all cylinders Pressure leak down test good Could it be the fuel injector for cylinder 1

[@michaelpersaud3113]

love to see the final repair video.

[@abcdefgh9138]

Great video, sir! To me, this video perfectly showcases the twists and turns of real world diagnostics. It's rarely as simple as one problem, or one failed part, especially when the customer/other shops have been involved. I'm wondering what you're using for a secondary ignition pickup? I've just bought a combination COP paddle/wire clamp from AESwave, getting some practice with waveform analysis.

[@coreysolomon6814]

Thanks Paul I really appreciate that pointer that will take me a long way thanks so much

[@theomnipresent1]

Near the end you speak of finding lean misfires with secondary ignition waveforms. Do you have a free video with an explanation?

[@robertmedina6875]

TestlightDanner lol I SAY THAT AFFECTIONATELY... LUV UR VIDEOS WATCH THEM ALL DAY!!

[@robertmedina6875]

Hack a Billy mechanic lol

[@Poochie43124312]

Paul You did say you wanted to not do a technical test. Just tried to keep it simple. Just to see if it could be diagnosed.

[@binnydinney9739]

“Nice easy fix”. “Misfire monitors are unreliable and inaccurate.” I think that Honda from hell definitely heard you because it kicked your ass. Good job. I couldn’t have done better myself. Try to trust the computer a bit more though, even though it is a fairly stupid computer.

[@rinzanb9715]

Paul I appreciate for sharing this video, I think you have done right approach to this problem. I knew this car definitely misguided to you but you cannot ignore when you are looking for a problem you have found the first problem from a spark plug itself and second from the spark plug lead. I don't think you have done a wrong approach. If there is a simple problem, of course you have to solve simple problem first. For instance, if you can treat a problem with a medication why do you go for a surgery. Man made problem is always a complicated one then a natural problem.

[@ringgoldxsickestx063]

Hey Danner. I may be making a trip up to RTI soon. I'll call you when I know the date for sure. Hope all is well. Keep doing what you do and thank you so much for everything

[@ScannerDanner]

Hey Bro. Thanks! Sounds good. Good to hear from you.

[@ringgoldxsickestx063]

I have been getting caught up on a lot of your videos and I must say it's just like being back in your class. It's so awesome that this channel and the other paid channels have such a huge following. Who would have thought 5 or 6 years ago you would have the exposure that you do know. I am so lucky to have had you not only as the best best teacher I ever had but also you have always been someone I could look up to and call if I needed help or advice on anything. Thank you man.

[@ScannerDanner]

B Carroll Cool man, I am glad you are watching. You always wanted to learn more and were eager to do so. That was obvious when you used to come to my garages with me, just for more knowledge. Hope things are going well with your new wife. Hope to see you soon. Definitely contact me first though. I took a term off at the school and won't be there until April.

[@hedaron3787]

I liked and subscribed because you didn't hold the answer for ransom. I appreciate that. I can't believe they shoved that Autolite in there. If that antifouler wasn't in play, I fear that could have been much worse.

[@mattm2411]

[@vitalyzhuk]

I had one of these (1999 Accord) that had an stuck open injector. Computer was keeping an injector open all the time. It needed a new computer.

[@AttilaTheHun333333]

learned lot from th video...THANK YOU!

[@milfordcivic6755]

Man...some people shouldn't ever touch engines. What would make someone go thru all that trouble to save $6? Poor Accord!

[@spelunkerd]

Only a great teacher would regret not capturing his accidental electrocution on camera. When you showed that spring I thought it was a helicoil. Fortunately not. It's interesting to see the strange things come out of used car dealer vehicles.The irony is that fixing the plug and wire correctly would not have taken much more effort. They were probably trying to get it out of the shop and they didn't want to wait for the right parts. Most of us would find that kind of workflow to be terribly dissatisfying....

[@gfriedman99]

The person that shimmed up the spark plug was a hack not a mechanic

[@michaelovitch]

They were maybe trying to cool down the cylinder with the device and a big spark plug

[@958kris]

Pretty nifty. Lean from a bad injector, but wet plug from a anti-fouler and a short plug boot. Is that right? No wonder it was hard to diagnose

[@ssndysanchez9365]

🌴🇵🇷 Hey thank you for making this video the is the model of my car Honda Accord ex 4 cylinder I have to replace the Cylinder knock sensor on it ..I did change the spake plug and wires also ❗ in the steering wheel belt... The Honda Accord ex are good car 🚗 doing maintenance on it key...👍🏽

[@dreamer2355]

This was a great video! I really enjoy your field work captured by film. However, I was slightly sad to read about the continuation to this case study to be only available on your premium channel. I feel as though going forward, people who are not able to subscribe to your premium channel for whatever the reason will start to loose all the great information going forward that made your past videos and teaching true automotive excellence. Your avid subscriber since day 1 of your channel.

[@ScannerDanner]

I know and I am sorry about that. The continuation was not a second part that I filmed in the field. If that was the case I would have put that here. It was a 3 hour lecture on what I did in the video as well as what I did wrong. So it was definitely more suited for my premium channel. I think it will be open to everyone soon. There are ways that people are accessing the channel using a VPN. Thank you for your support my friend and sorry again to disappoint,

[@JOHNPHUFNAGEL]

Have you ever Not been able to figure out the problem? and if so tell us why. Great video Cant wait for the lectures

[@ScannerDanner]

Of course! I would be lying if I said no. But I have fixed them all in the end except for 2. One was a caddy that would intermittently blow the muffler apart every few days (pretty sure it had a worn distributor cam gear) and another was on a Ford with an EGR flow code, but that one was taken from me before I could finish it.

[@JOHNPHUFNAGEL]

ScannerDanner lol when I was a kid my dad had a 72 F150 I would drive on the farm.. Going down hills I would shut the key off and pump the gas pedal 2 or 3 time and turn the key back on WoW that was loud My old man put 3 mufflers on before my lil brother told him what I was doing Lol

[@gailtaylor1636]

I missed the annotation at the end that verified the injector WAS in fact the issue but would appreciate a response to my other question anyway.

[@jamesb.9155]

So was the #2 injector the cause of the mis-fire or not? Nice array of technical diagnostic tools you got there, along with good theory and low tech short cut tests to eliminate standard issues like faulty wires, plugs and compression balance. Sometimes you get lucky and sometimes it's a bit more complicated!

[@ScannerDanner]

yes, it was an injector issue

[@Ehrokyn]

Excelent video with a lot of info. I was thinking the same thing about fuel trim. One question, is a good practice to diagnose injectors by reading their resistance? Could that popped the problem out? Thanks Danner.

[@ScannerDanner]

+Emmanuel Morales resistance tests only show part of the problem and even then you can miss winding problems based on temp. So current ramping is a more preferred test but even that will not tell you flow problems.

[@Ehrokyn]

+ScannerDanner I see, thanks Paul.

[@edenmotorsport405]

Good vid . I laugh when i see rings on the plug. What is your brand laptop?

[@mohammedzaman3770]

Hello Mr danner, I have been following your work for some time now.I am a trainee technician at ABM Motors in West london(United Kingdom).Here in England german diesels are the most common used(Audi,VW,Merc,BMW).How often do you diagnose no start conditions on german cars which are far more complex then American and japenese cars.Could you do a video on German diesels.

[@michaelsieber6601]

Mohammed Zaman Lol no they are not

[@Foxieluna]

I have a 98 Honda Accord. Would the #2 be the same place on my car? I have a misfire code on #2 but don’t own the test tool you used in the video

[@prnd21zinman37]

Classic scenario of "bad miss, should be easy, wont pull out the scope." Forty minutes later still scratching head on where to go. vs. "bad miss, go right to scope.' I think the scope wins on averaged time, all the time. So for me, if the visual doesn't clue me, out goes my scope and pick up. Took a long time to break my old habits of jumping too much. After all, we're not in the gym working out. Like you said many times, "time=money." And my pigs gotta eat. Wheek wheek

[@cherepa1992]

Man you are awesome,just keep making video!

[@jimbobs777]

Oil blow by ..... anti fouler just moves the gap farther away from the piston ..then maybe the oil will not reach the gap as easy ... the gap is in a chamber that keeps the oil from reaching it .... it does work sometimes ..but the spark is a lot less efficient... by up to 40% ....

[@reweydewy]

You could have just swapped #2 and #4 injector? Then do a rpm drop test?

[@spanionneo]

Thanks Dan. That was educational.

[@linnadawg]

On most Honda’s, to prevent the car from starting, pull the efi fuse under the hood.

[@peanutbutterisfu]

In a situation like this I would have ohm'd the injector, 9 times out of ten just checking ohms will be a dead giveaway. You could try some propane, carb cleaner or brake clean to see if it straightened out. If it straightened out I would have popped the rail up enough and if all the injectors were still in the rail Firmly I would have some one crank it over to see if the injector is firing or just swap the injector out as these are pretty easy.. Mac tools makes a banjo bolt with quick connect on it that screws into the filter. It comes in the basic fuel injection kit I think the whole kit was like 100 bucks and actually covers a lot of stuff. Very Cool how you used the lab scope but if your flat rate you gotta move a lot faster lol. The biggest problem with kids when they come from school is transforming into the working world which is 150% different from schooling.

[@andyfanshawe]

Hi Paul. How do you charge for something like this? I'm sure we have all been there before. Charge for 2 hours time + or eat it and charge for an hour? I've certainly been here before. Forgotten something silly and gone on for ages, when I shouldn't have!! I certainly can't charge customers for my misdirection! Wondered what all you guys do in this situation. Andy.

[@ScannerDanner]

I only charged an hour, mainly because I was filming too. I felt that was the right thing to do in this case. Plus the extra time was really my fault. I just wasn't thinking clearly. Hard to charge extra when it's your fault.

[@johnkimmel2612]

All the refinements(?) done by previous techs (?) would definitely throw off one's usual plan of attack on tackling this issue. I remember purchasing a used 1992 Stanza from a workmate which seemed to be decent vehicle and ran good. Problem was that it failed PA. Emissions for excessive Nox. I finally noticed it had the incorrect NGK plugs. The electrode reach was not correct.

[@ssndysanchez9365]

🌴🇵🇷 Hope you could make your next video on replacing cylinder knock sensor on the Honda Accord ex 4 cylinder Thank you for your video 🤗

[@TradeDiagnostics]

I have seen this type of issue with Mitsubishi Lancer where the tube on the COP was to short and didn't reach the plug, the amount of parts replaced on this car before I got to look at it was ridiculous including cylinder head!!!

[@larryordine7542]

Frankenstein plug adaptor. I would have gotten a wire first and read the codes. Otherwise good. The F23 a1 engine internals good for 500,000 miles. The injectors get clogged and EGR valves and ports. Did the codes say lean misfire?

[@ScannerDanner]

This ultimately was a lean misfire from an injector issue (restricted)

[@larryordine7542]

@@ScannerDanner Great to see a dropped cylinder test. I learned that 50 years ago on my Triumphs, Jags and other British heartaches and it's still good for all classic cars. I just always start with OBD codes on anything with a port. Saves time and that high voltage feeling in your hand. The jackass that mickymoused the wrong plug and wasted all that time and screwed up the threads to make the wrong ignition wire fit to save a few bucks should be jailed.

[@billsmith2212]

Since it has a lean misfire , would the fuel trims go positive ? The computer would add fuel to compensate . And how much would the numbers go - above 10% ?

[@FilmFactry]

Great and very clear info!!!! 5 stars!

[@apollo11capcom39]

Can you explain exactly how you're using your test light to prevent you from getting zapped? I don't understand how that being there is changing anything.

[@ScannerDanner]

It's a better return path back to the coil than i can ever be! I can even touch the metal park of the light without being shocked. What leaves the coil must come back to the coil, so it's looking for the easiest path.

[@travyb1401]

Man Autolites in a Honda.. NGK only for those guys. Unreal

[@AhmadGalalYT]

How much power does the car loses when it misfires and runs sluggish?

[@ScannerDanner]

depends on the miss. How many cylinders the engine has, how many cylinders are misfiring, is it constant or intermittent, etc, etc

[@AhmadGalalYT]

ScannerDanner Alright, thanks for teaching us and for the detailed information :D. But bro i just have one more question and i hope that it don't sound stupid, what will happen if i kept my car misfiring, running sluggish for a very long time without a fix?

[@ScannerDanner]

you risk melting the catalytic converter. depending on the type of misfire, you also risk mechanical damage to that particular cylinder from washing the oil off of the cylinder walls with gasoline that never gets burned. Then you risk adding this fuel to the crankcase (it will run past the rings), which will dilute the oil with fuel, then premature bearing failure can happen. Nothing good bro. Unless it is a mechanical issue and the engine needs rebuilt anyway, I wouldn't keep driving it.

[@AhmadGalalYT]

ScannerDanner Alright :D, Thanks alot for helping me :D, I have 4 cars and one of them was a misfiring honda odyssey 1995 v4 engine, it was a cylinder 1 misfire, i removed the spark plug and inspected it and saw that it was full of carb, so i replaced it with a new one, started up the engine it was still misfiring, then i found out that it was a worn out spark plug wire because the wire on the cylinder 1 was burned and...can't explain how it looked like, but anyways i replaced all the other spark plugs too to make sure no near misfire in the future ;). I subscribe :D

[@ScannerDanner]

cool man, good find and thank you!

[@SuperStarCustoms]

ScannerDanner Premium You mentioned Autolite spark plugs do not belong in Hondas. Can you explain why? I always hear NGK for Asian cars, Bosch for Euros, AC Delco for GMs etc. But, I would like to know exactly why. What is the difference between the Autolite 5224 and the NGK ZFR5G-11 for this car. Thank you for your great vids!

[@ScannerDanner]

For the aftermarket guy that works on 40 different car lines and seeing MANY issues from incorrect spark plugs (even though the manufacturer of the plug says it is the correct application). I want the factory plug only.

[@SuperStarCustoms]

ScannerDanner Good enough for me. Thank you.

[@SS-U23]

Number two spark plug's thread looked stripped off. Why in the world putting too many washers to make the spark plug fit this engine? that is funny. Thank you for the video.

[@chadfordham1]

Did it turn out to be a blocked injector on cylinder 2? Also, were you using an incandescent or LED test light on the dizzy cap? Cheers!

[@ScannerDanner]

Yes, injector issue and the test light is an incandescent I have it listed on my Amazon affiliate page if your interested. It was like $20 www.amazon.com/shop/scannerdanner
