EXCELLENT video. Not only do you show it being checked, but you actually TEACH us how to check for ourselves. I wish all youtube car videos were like this. Thank you for making it.

Thank You SO MUCH! I was able to narrow it down to a bad spark plug in cylinder 3. I replaced all 4 spark plugs for 20$ and runs great! Saved my mom money by not bringing it to a shop. THANKS AGAIN!

[@jeffclark2185]

I have had my forerunner at a certified Toyota mechanic shop. for at least four years similar situation and no one can tell me exactly what’s going on. Your video has been great and explaining and diagnosing the misfire. I now can’t wait to try it out thank you so much.

[@rickeymitchell8620]

Thank you very much for the videos. presented in a logical and realistic way. i like how you use customers vehicles for the repairs, can't get more real than that, real world situations.

[@bearsrodshop7067]

Picked up an 06 CTS few months back. After engine poped on, found a P305. Been driving, but now time to correct, and this video really helped. Bear

[@mikemcelveen2973]

There is a leak in the middle cylinder coil boot. High kv under load induces the spark to go to ground via the spark plug port. No load kv at idle will allow current to flow through the spark plug. I would love to work with guys like this. Great video I'm sure this will help a lot of newbies.

[@skillz1855]

This guy reminds me of an engineer I trained with at Acura,B4 I went on to BMWs. he has a very detailed way of explaining things to beginners

Thanks for sharing. You are such a good teacher. I experienced the same problem on my Toyota RAV 4.

[@betoandkathyperez]

Thank you so much it really helps me out i hade the same problem with my car take it to 3 mechanics and none of them told me what was the problem they just told me to take to the dealer cus they couldn't find nothing so after a couple of videos i finally found wht was the problem thanks to you i save a lot money

[@meetmax]

this was actually very very helpful and i learned how to test spark plug wires easily

[@davidrowland7918]

He described that better than I've ever heard anybody on KZbin

[@carlos92161]

Thanks for teaching us personally I appreciate it your time really valuable 👍👍👍👍

[@coycarlson4979]

Great demonstration of logical troubleshooting 👍 . I believe the cause of the misfire to be one of the two plugs fed from the center coil which was not contributing under load. It is possible that maybe the center coil is breaking down under load - however when you lifted the center coil out of the spark plug well - it appeared to have a good spark jumping / arcing from the spark plug boot - so I am thinking that maybe the center coil is still good. 👍🧐✌️✌️

[@Sam-de2le]

Really nice video I think you showed us that we really may not even have to use the paper clip trick at all since by pulling out each core individually gave us indication of spark and yet did not indicate which cylinder was mis-firing until you raised the core itself. Simple enough for me. Thank you much, Keep up the great work!

[@Ag3nt007]

You could see the hoses actually stopped vibrating as much during the clip test

[@davidhammett1323]

Thanks for your great videos. You do a great job on videos. I enjoy them a lot.

Excellent video and great diagnostic skills.

[@everythingisvibration]

Great Video !! All of your videos about misfire helped a lot. Thank You very much. Saved me a lot of time & $

[@tomreyes4908]

You gave me a good lead on how to fix my issue. I started per your video but also placed a timing light at the end of each wire by the plug and found on wire was bad. Replaced wire and runs as smooth as new. Thanks for posting.

[@realfixesrealfast]

glad it inspired you to use creative thinking, thanks for posting

[@mikalvanger6895]

wow that's a new trick i never thought about using wires..nice video good job

[@TheDadofsix]

Wow great video. The rear bank of cylinders on my Ford Edge prevent access to the rear plug’s coils but it’s good information for the front three!

[@venomhemi3914]

Now that's a good instructional video, I subscribed right away thank you!

[@stewartvclark4008]

Excellent diagnosis, thank you

[@livinlifefl411]

Man. My hemi is misfire crazy with zero codes. New motor. New plugs. Old coils. Runs great. Only misfires under load around 3k rpms. This makes me think i have a bad coil. Gonna test them like this. Thank you.

[@77zmun]

I just learn something new today. Good vid

[@scottytomcat4267]

Absolutely great video thank you so much

[@linodoy]

Thanks!!! for share your experience! I did have a problem with one coil in my Hyundai, I did the test only to a normal speed; I could not find the one that did not work. You help me to find it out the one that is not working!🙂🏆🏆🏆

SPARK PLUG! | Excellent that I went to 1 year of Automotive Tech school, but never seen that Wire method.

[@desertratsss]

Bravo, just went through this. Thanks.

[@rayharkins14]

great learning video. you are a natural instructor. thanks

[@ownsnine]

EXCELLENT instructive procedure for spark wire coil and plug diagnosis. the ONLY flaw in the whole video is your statement that spark is coming UP from the bottom of the plug. It is not, it is coming DOWN the wire TO the plug FROM the coil and choosing the apparent path of LEAST resistance and going down the side of the plug in the carbon filled crack to get to ground where the plug screws in to the head. So it does not come UP FROM the ground point it comes DOWN from the coil Voltage travels + to - not the other way around.... But needless to say that changes nothing if someone does not know that it will not hinder the purpose of this video in any way anyway. Absolutely fantastic video other than that pick at you point well done. I am a Mobile Tech been doing it since 1994 i actually helped a customer avoid spending money with me and CURE his 1997 3.4 toyota misfire with THIS video as his aid (send him the address) so again, great job thanks much.

[@realfixesrealfast]

thanks for your observations and comments.

[@ericrigoroso4445]

you guys are awesome! thank you so much and god bless........

[@fixr]

You could swap the coil pack to see if the trouble followed to another cylinder, and if it does... coil pack, if it doesn't... spark plug. Great video illustrating basic/advanced troubleshooting skills! I think I'll subscribe!

[@PrometheusGroup777]

Impressive evidence thank you

[@josephdesimone865]

coil 2/middle, under no load or just on idle still was firing when you pulled the s.p.boot allthe way out.....i am thinking bad s,plug or coil is failing under load...hence need coil. you guys are a big help,,,,thanks joe boston ma

[@struebel232]

I want to say bad / dirty injector, or bad valve(s) on that cylinder. Need more tests to confirm. ( Compression test that cylinder to determine if its a valve) Great Videos, Great work... Keep Them comming! Like to be always thinking!

[@withwingsaseagleeyes]

could be the coil, but really could be the wire as I found in my problem with a 2000 Chrysler Intrepid. I did the same but then switched the coil on the misfire with a coil from one that was firing to see if it was in fact the coil, but all coils on that side worked.

[@CARRJ142]

Another great video.

[@derossilibya]

Thank you sir this was a great video

[@ghettospacefsh6251]

Thanks so far. Number 8 when under a load seems to run good but idle and to 30 miles an hour smooth out. Engine light will not go off so no tag Mike chattanooga

[@anthonyguerrero9084]

Thanks! This helped!

[@spelunkerd]

When you shorted the ground wire the flame was the same size on each. As you pointed out, if a wire is bad the flame would be bigger, because of more resistance in the natural pathway through both plugs on that circuit. If either plug was bad, I would expect a bigger flame as well, for the same reason. So, those of you who say it's a bad plug are ignoring that part of the evidence. Of course, inspect the plugs, but I think it's something else.

[@marilynparker46]

Very cool. I could understand and follow very well. :) Sounds like you need a plug in the middle.

[@jlmusic1469]

Coil #3 or passenger middle is bad. Great lesson. Thanks

[@DCunknownissue]

excellent video! now i wanna see you do this on a 5.4 expedition

[@martingarcia8034]

Excellent video thank you

[@saltyseascott]

Very old school would call for a coil replacement. I once had a bad coil on a 1959 triumph motorcycle. I found myself driving into eagle pass, TX to a general store and bought some birthday candles and a roll of electrical tape. Meled candle wax into the hole and wrapped in electrical tape and the bike ran very nicely after that. Back in the 60's thats all there was to eagle pass.

[@24fan24AARP]

Very interesting, thanks!

[@johngunter1811]

I have a ford e150 5.8 very smooth until held steady 35/45 then slight missing. New ignition control module plugs wires distributor. Very smooth until high gear.

[@werksalot]

Great video , I couldn't tell for sure but it looked like the spark plug boot was wet . So I'm saying the spark plug tube is full of oil .

[@screwsnutsandbolts]

Awesome channel Subbed ! 👍🏻

[@samweaver6632]

Too awesome I learned something today so it's a good day to me,,I'd say bad boot,,short or something

[@meesterp]

I'm surprised that you can pull the coil pack off while running without ruining it. Looks like a good diagnosing option if it doesn't cause internal short with the pack being ungrounded.

[@andrenj1970]

great videos, more to learn

[@hectorlebron3109]

Great video awesome thank!!!

[@danielledda1460]

great ,.but can you change the one coil or go ahead and replace ALL

[@daeshbagcentral5298]

Informative,good vid.

[@Camaro4681]

Spark plug or a cracked plug. also check for carbon track on spark plug and boot.

[@camaroiowaguy23]

i have a 97 bmw 5 series and my engine only misfires under load.. ill have to try your load test when the weather warms up. i appreciate the idea.

[@Henry-cy2kk]

Subscribed! You rock.

[@salvadord.magana1319]

That's a pretty neat trick with the wire

[@de-jf6xp]

thank you sir ive learned somethin g today thank you

[@momosikihogoromo7886]

Thanks for your video

[@f.w.1318]

will this work on a 2005 f150 5.4 3v by lifting the coil?

[@jackparker8686]

Very important .. As a pseudo mechanic.. I cut tip of boot off as far as I felt safe. To get them to snap on. And thus began firing my spark plugs. On the side where I felt that catalytic had melted down. Or became a second sun..

[@LJT9393]

I thought the background was real in the beginning and thought “man that guy is good at sitting still” lol

[@AJ-bi2rt]

Good man. Thank you

[@Hashassin95]

Yeh a most excellent video, hopefully tomorrow I can find my dud coil, thanks matey 😇👍

[@nathanielreid4967]

I would swap the coil pack in the middle with any one on the out side, if the misfire go to the outer cylinders then I could say it is the coil pack that is defective. However, if it remains in the middle cylinder then I would conclude that the spark plug is defective.

[@DFWAuto_Hack]

hello, i read this and agree with you. however, i have an annoying one. what if after concluding that the plug is bad, you replaced the plug on the bad cylinder just to find the misfire still remains at the exact same cylinder. would you suspect that cylinder to havr a bad compression or a bad PCM??

[@VICTORESPINOSA7]

then its a bad fuel injector

[@POOKIE5592]

Bigvik Or a burned exhaust valve.

[@charlesrohrer667]

Oops burnt valves.

[@josejuarez2452]

or change both coil and plug
