[@rjright7373]

My customers issue was a bad coil, replaced, and a month later the new coil went bad which was, fortunately covered, since she knew them and was a great talker. Further, the valve-pan cover gasket was leaking oil into the spark plug area and shorting the plugs out causing the random misfire. Finally, the (braided?)ground-wire from body to the motor was weak (copper was heat-burnt looking, brittle, and easily resolved with replacing and cleaning surfaces. This Honda engine was easy to work on and I appreciate learning new tips from your videos. I have the 720Pro and do back-yard stuff and appreciate learning new techniques to make diagnostics faster to save me work and customers money.

[@aliciarobin7637]

I want to thank you so much for making this video. I'm in the same boat with my 2005 EX-L, which ironically is identical to the one in your video. After 2 Honda dealerships and an independent shop gave me the run around, I had almost given up hope that a proper diagnostics could be done. Going back to said "lazy" dealership #1 armed with my new knowledge and pray that it hasn't been going on long enough that it's burnt a valve. Oh well, if it has, they'll be fixing that, too....thank goodness for extended warranties! Now I'm going to watch the rest of this series!

[@GoTechTraining]

Thanks Alicia! I hope you have better luck the second time around. Always better to go at it armed with information. Good luck! Mike Becker, Senior Technical Services Instructor

What a great video! My 2003 Honda Pilot is throwing error codes for cylinders 4,5,6, and the "general misfire" as well. We bought the car with 100,000 miles on it, and the service records show plugs were done, so I was suspecting a stick coil, but now I think it is the valve adjustment. I don't have the diagnostic gear you do, but I was really impressed with your thorough, logical approach. Nice work!

This video makes all the sense in the world to me and I appreciate the detail in presentation and clarity in communicating the lesson. Most of all, I now have a direction for repair with confidence that the problem will be resolved. Well done Sir and thank you!

Any update on your problem and/or repair? I’ve got same codes (and random misfires) on my 06 Ridgeline with 130k miles. Dealer replaced timing belt, water pump and did the valves. (I replaced all plugs, coils, and pcv valve with OEM parts). Still get random misfires occasionally (cleaned EGR channels but not EGR valve). Help!

[@Jose-xb6st]

@@axjohn have to try with the injectors?. EGR Valve

[@axjohn]

Jose yes I ran a couple of bottles of Redline Fuel Injector Cleaners in two consecutive tanks of gas. I couldn’t get the bolts loose on the EGR valve do I haven’t cleaned it or checked it yet. But I just left my indy Honda Acura repair shop-they loosened them hand tight for me! I’ll remove the valve and clean it after the engine cools down later tonight. I cleaned the EGR holes at the top side of engine and I think I loosened a piece of carbon that has stuck the EGR valve open which I’ve read online can cause a lean signal to the computer due to too much O2 and then computer adds more fuel to compensates, hence my lean code and running rich codes and misfires upon cold startup. That’s my guess. Will update.

First-time viewer. Super impressed with Mike's knowledge and presentation (I'm a professor, if he were my student, he'd be getting an A). My '06 Odyssey with 220k just threw these exact codes and has the exact same slight roughness at idle. Mike's diagnosis is the bomb. And, he showed me that the proper diagnosis is something that I don't have the time or tools to do. If I go in and have someone like Mike come to me with this kind of information, I'd be totally confident to make the decision as to whether or not to put money into this old van (oh, mine also needs struts, axles, and a couple of other things).

Fantastic video and great explanations. Anyone fixing cars needs to understand the underlying fundamentals. New subscriber(also master/L1) grateful for some refreshers. As the diagnostician at my shop, I break the scope out on occasion, but this ticket also shines a light on some of the problems with boots on the ground and flatrate. At this point with a Honda + miss on front bank, I'd just sell the adjust. If I was wrong my shop would (yes, really!) eat the labor. If you eat 2 out 100 you still come out way ahead. For the FNGs out there, further general confirmation can be had by holding a paper to the tailpipe on a Honda and feeling for a pulse. With this particular car it likely wouldn't be absolutely conclusive given the specs, but this issue is seen across all Hondas with adjustable valves and a sure tell on the 4 cylinders. Re: Cam gears not installed on shafts correctly. This has become more common as more manufacturers use press fit cam gears instead of pins. If you get one of these in, step one is to have the owner asked if the car worked on recently. On something like a Mazda 3 installing the crank pin tool and pulling the valve cover to install the cam bar is generally going to be faster than breaking out the scope and navigating the schematic to find your pin hook ups. You are absolutely right about spark plug choice. Gotta see NGK or Denso. Can't count the number of cars I've fixed by pulling out a brand new set of +4s or splitfires and installing the OEM plug. Great video, thanks.

[@GoTechTraining]

Hey A B, glad to have you on board!!! Welcome to the channel! All valid tests man, I can tell you've lived the life for a while :) I despise these press on gears. I had a 3.5 EB F-150 that the cam reluctor shifted on the cam...stupid issues that shouldn't really happen but they do. It's amazing how good some of these companies are at marketing their "special designs." There is a reason why NGK has the most OE market share and those "others" have little to none! Again, thanks for watching! Looking forward to more great comments from you. Mike Becker, Senior Technical Instructor

Absolutely one of the best diagnostic videos on KZbin I’ve ever seen.

[@GoTechTraining]

Ouch 2010 coverage is no good. Cost to update is almost as much as some new tools. Always looking is right, I am too! It's harder for you in Canada I suppose.

I have a 2007 Honda Polit with a P0302 code and came across your video as I was looking to see how to proceed on my Honda. In short I was so very impressed by your presentation and knowledge, so much so that I watched all 3 parts. A valve adjustment is way over my head and the tools I have to diagnose or fix, but you did provide me with the knowledge to go to my mechanic and know what to ask about if a valve adjustment is required. Can't say enough - GREAT video. Thanks

[@smottiebug7518]

lol, its not like rebuilding a transmission. The tools needed… $3 feeler gauge from auto parts store $5 allen wrench set $10 socket set from harbor freight. And A small amount of brain power to remember how an intake manifold and valve covers go back on. Its not hard to do,, but it does take a while and is kinda tedious to adjust 24valves. (usually, only the 12 exaust valves). But its pretty easy to do and check them yourself for peace of mind. (without all that fancy waveform devices.) especially if you know they are due, because you haven't had them checked in like “ never” or “forever” +100k miles ago.

Hi Mike. I have 2013 MDX. It has s misfire in cylinder 5. My error code is P0305. 240,000 kms on it So I have done the following 1) Swapped Coil and Plug from cylinder 5 to 6, code remained P0305 2) Tried Seafoam, Redline S1 and Mystery Motor Oil treatment in fuel tank and Engine, issue did not resolve. 3) I got compression test done and it showed low compression in Cylinder 5 120 PSI vs 170 PSI in cylinder 4. Then I got an auto body shop to do all 6 comparative compression test and it came compression is only 25% in cylinder 5 and approximately 75% in cylinder 6. Cylinder 1,4,2 were 100%, cylinder 3 was 92% 4. I took it to Acura and got valve adjustment done, they said it was loose intake valve. It made engine sound alot better and I felt it got power but misfire still shows in p0305. I watched your video and have read forums. Now I am not sure what to try or do next. Any advice and help will be great. What do I try next?

Nicholas, many people do. I like the vacuum gauge. It took less than 2 minutes. I like to look for that rock steady needle.

Im sure you already know about the fuel injector best to unplug if possible its more for others but you may have stated as im still watching.

[@GoTechTraining]

Hey Mike, that makes sense. Too much time running could wash it out. I did not unplug the injector on this one. Hard to say if the PCM realized it was missing and cut the injector. I suppose I could have checked that. If I remember right the injectors were very hard to get to on this 3.5. Mike Becker, Senior Technical Services Instructor

Veru good videos mike, one question to do the valve adjustment?the engine has to be rotate clockwise or counterclockwise? And how do you which way must be rotate it, thank you mike, and cheers from ontario California.

[@GoTechTraining]

Hey Everardo, thanks! Most engines rotate clockwise, but that is not ALWAYS the case. One way to know for sure is to use the starter to slowly spin it over to verify which direction is normal. You may also find information on the direction of rotation in your service information. Mike Becker, Senior Technical Instructor

[@davidpearson524]

[@GoTechTraining]

Hey Abdie, thanks for watching! Who knows what the future holds :) Mike Becker, Senior Instructor

[@joeclark8029]

hi mike great video!! question 1... can you get intake vacuum reading by taking the baro number and subtracting the map number to get intake vacuum reading? question 2 why is the map reading not actual vacuum and what is it measuring because it says map vacuum? question 3 what do you do if it has variable valve timing and need to take incylinder transducer reading but dont want variable of valve timing, isnt that a concern? im sure alot of people are wondering this or they havent thought about it so could you please help us out with these questions. much appreciation

[@GoTechTraining]

Hey Joe, thanks! For the minute that it takes to hook up my trust gauge to the intake manifold I prefer to grab a really quick manual reading rather than trusting the sensor. For VVT you can unplug the solenoid to verify the VVT isn't being phased, but you have to hope/assume the phaser is ok and not partially mechanically stuck.

[@robertcook4399]

Hey Robert, no I don't see a way the 2 could be related. I think these are 2 individual problems, but i'd recommend taking care of both at the time of tear-down! Mike Becker, Senior Technical Instructor

This has been happening to my 2006 Honda pilot. When I looked into this before, there is actually a service bulletin regarding this issue of valve lash adjustment and resetting cpu.

[@GoTechTraining]

Hey Ekimzaga, it's actually right there in the owners manual that they should be inspected/adjusted at a certain mileage. Mike Becker, Senior Technical Instructor

Great video 👍 would you able to explain how you added power point onto the picoscope. Would be greatly appreciated.

Hey Sherwin, thanks for watching! I took a screenshot of the PICO capture using a program called "GreenShot". I then copied it into PowerPoint so I could do my hand drawn overlays. It works really good that way. Mike Becker, Senior Technical Instructor

@@GoTechTraining thank you very much. Keep the up the good work

[@SG-go9zc]

Awesome lesson. Thanks. Question: why would the speed of the exhaust pressure/vacuum release cause the engine to run rough? It doesn't seem to effect the intake, compression and firing events.

[@GoTechTraining]

Hey S G. It's not the "speed" that we are seeing. It's the time. If the exhaust valve opens early it's cutting the compression stroke short. Engines are super fine tuned as to when the valves open and close. Any discrepancy in that can and will cause divisibility issues. Mike Becker, Senior Technical Instructor

It's like your toes hitting too early when you are running.

VERY informative young man! ive seen this many times. ive sold valve adjustments on these and misfires still happen... Honda has a class action lawsuit on this engine. Ive heard the rings crap out on them. Honda puts a new long block in them and valve job and adjustment on them... kinda messy... also the valve cover plug well seals leak oil into the plug well tube and does the same thing.... its like pissing in a fan.....

[@GoTechTraining]

Hey Mike, thanks for watching! Yeh, i've heard about the rings being bad. I think that's on 2010 and up though. 2006 wasn't too much of an issue for that. Mike Becker, Senior Instructor

[@mikem1014]

nice video... had customer with 2007 Honda FIT .... stall issue ....when cold.... back out of drive way after one stall... you start back up an never did it again till next cold start . valve adjust fixed it but did kick my ass for couple hours diag time ....

[@GoTechTraining]

Wow the valves were bad enough to cause the stall! Mike Becker, Technical Services Instructor

Thankfully for the job

Hey Mike! How's it going? Happy New Year to you! Thank you once again for your awesome videos! Your knowledge is greatly appreciated. I have a situation where I'd really appreciate your opinion please. I have a 2005 Honda Accord V6 with 66k original miles. Its has codes P0300, P0301, P0305 and P0741. It has new correct Denso plugs in it. I haven't done anything to it yet because I have it for a couple days. Plus I'm stumped as to where to begin because of the low miles. Your opinion and knowledge will once again be greatly appreciated! Thank you for your time Mike. I hope you have a great week.

[@GoTechTraining]

Hey Edward, thanks for watching! All is well here, thanks! That's the motor with the egr ports that plug up I think. Take a look at that. Low miles, maybe it wasn't driven to the point it got cleaned out all the way all the time. Mike Becker, Senior Instructor

[@edwardthayer9386]

@@GoTechTraining and you believe the causing the problem with the transmission?

[@philsmobilewelding]

I got the same codes on my Honda Od and customer has never done any Tuneups at this point at 220k . Says he’s never had any trouble with shaking or engines lights until now? Is this still a valve adjustment protocol? Thanks love you video , your a gifted teacher 🙏👏never stop teaching 👍

[@GoTechTraining]

Hey Phil, honestly, i'd probably start with all of the tune-up stuff. Spark plugs, valve adjustment, etc. Mike Becker, Senior Instructor

[@jptrainor]

The exhaust valves on my 2010 Odyssey EX-L (vcm engine) were all a little loose except cylinder 5 which was slightly tight. Every intake was a little loose. That was the first valve adjustment for the vehicle and was done at 146k miles.
