HONDA V6 MISFIRE

[@jonathanwarren9594]

I just got my 03 accord coupe v6 back from the shop, its been misfiring a while and they said i havw a bad cylinder no.2, he said probly need new motor, since mine has 246,000, but after seeing this video it almost makes me wonder??

[@MrSamPhoenix]

Honda’s V6 design is robust. I’ve worked on them & they’re very easy to work on. A misfire is usually an indication of a bad ignition-coil. If it’s something worse that means the owner/user of the vehicle ignored the initial problem(s). But man, a chipped valve is unheard of!

[@sagemaster7534]

Oh look we have the asshole expert, oh how can you not like my favorite engine but oh it's your fault it's in a bad condition, bro if your two cent are being a pretentious little show off then what help are of

[@trendynick3650]

I think this is a common problem with the j30a4. I’m dealing with misfire at cold startup and then runs smooth until the car gets warm. Then a random misfire at WOT. Pretty sure it’s a coil but I’m suspecting it needs a valve adjustment for cold startup misfire. Love the work environment!

[@Rob-fx2dw]

To determine if valves area problem do a compression test dry first then add a little oil to the cylinder thru the spark plug hole and do he test again. If it increases greatly then it is rings - otherwise it is a valve problem for sure.

[@brasanford1]

Customer done a good job on the timing belt even applied the service sticker under the hood

[@joemikos900]

Great video James. I know they take time but we appreciate it. Please keep em coming. Merry Christmas Thank you

[@Carlparishhonda]

Ignition coils replacement stop my Honda Fit from miss fire with over 140,000 miles.

[@drtokubuns]

So I had this happen to me and after replacing the plugs, coils,wires,fuel injectors,o2 sensor,egr valve and redoing the valve lash, I found out that it was the head gasket

[@stevegunderson2392]

I have a 2000 Acura 3.2 liter, 97,000 miles on the clock....seems like the same issue....I checked the valve lash everything was on spec 0.3mm exhaust and 0..22 intake....then I discovered that the spark plugs were loose....tightened them to 18 ft pounds and three weeks later the same thing...tightened them to 25 foot pounds and checked to make sure there is a good ground connection to the motor from the battery...I have not had a relapse on this issue for the last 6 weeks....how do spark plugs become loose....??

[@Badgertronix]

Lots of awesome info. Great work, looks like a lot of fun

[@jeffreyheelan4850]

Good video bro. If any entry tech watched this video , like it and pay attention to the valve adjustment he shows. It’s verry important! We need more techs like this in the world. Knowledge is power. And I feel like I’m nick in my shop the way my boss comments my tools too. 😂😂😂

[@EXOVCDS]

Sounds like you have a fun work environment with your coworkers! Some shops get stuck with a guy that keeps watching what everyone's doing, tries diagnosing for everyone and has the loudest impact gun!

[@jamesdanner7850]

+Thomas EXOVCDS it can be fun. If I ever get some of your glasses, me and nick could have a comedy show

[@EXOVCDS]

James Danner Looking forward to it! I sent your brother a Euro plate a while back... thought about sending you something. Where can I find your mailing address?

[@CashApp-HelpMeStayAlive]

Yeah We call that Guy Tim Around Here . Tim the tool man Tailor

[@quangpham2281]

Must be you right? ROFLMAO.

[@olderrol1968]

Throw a female in the mix. To add a little drama and confusion.

[@ro-longo3697]

I loved the flaps on the tail pipes.

[@jenniferburgett8328]

We've done all this plus more on my 01 & it's still showing misfire on all 6 & p1399. After we work on it, it's clear of codes & when we crank it up, rev it to 2k rpm the cel will come on & if it doesn't, driving it will cause it to come on. It also has that rough idle like that one

[@NewLevelAuto]

Dollar bill on the tailpipe next time ! Great video As always

[@jamesdanner7850]

+New Level Auto nice. I could have Paul over next time with hundreds. Ha

[@zheloshuvieraheshadonelkhu1874]

[@Force1Com]

I'm surprised the engine would run that good with a hole in the valve. I have a question about the miss... how does the problem the car have cause the other cylinders to miss?

[@rosieclark3661]

It’s a Honda that’s why it still ran so well even with a hole in the valve try it with a Chevy and I’ll bet you’ll be calling a tow truck 😂😂😂

[@CravinMorehead420]

Haha! I almost fell asleep before you said that. Nick will do well with a mentor like you..

[@NCPDFSB]

good one james, talk about detonation fracture!

[@rrmech11]

nice to see a video from you James

[@osc1968]

That valve burn because car been driving with tight valve for long period of time and never adjusted especially in this v6 honda motor

[@ryanstevens9225]

I have an 04 with 149xxx the belt was replaced at 100k , only when I FLOOR it I get the multiple misfire code. I've replaced all plugs and coils and I thought it was fixed until a few weeks ago. Car drives perfectly fine and it doesn't feel like a misfire I just get the flashing light. Am I looking at possibly same issue?

[@zachbento3798]

Same happenes to me when going over 6k rpm check engine flashes and sometimes throws cylinder 1&5 misfire changed plugs coil still does it only whel flooring it did you ever find a solution?

[@yt-user03561]

@@zachbento3798 I had the same exact issue. My 04 has 119k and I did all the coils, plugs, timing belt and vavle adjustment only 10k ago and when I floor it until vtec engages the CEL flashes for about 10 seconds then stops. Scan tool showed 1 & 5 misfire + random but only as "Pending DCTs" but nothing in Permanent DCTs. Maybe it is just a glitch or I jumped timing for a split second? The engine runs and feels fine except when the I turn on the a/c then it feels a little rough. Could be mounts because they are aftermarket from Anchor. I also notice that once in a while it has a hard start/no start when it's cold which I thought was a flexplate issue. The car otherwise has been really good but in turn it makes it hard to chase these intermittent issues with less than obvious symptoms. I just don't want to wait until my cat completely fails or my engine blows up to do something about it. Still on the hunt for some answers to these problems.

[@ThePhoton6]

That same thing happened to my 06 Accord a month ago .. on cyl 5 .. same hole in the exhaust valve. ..at about the same mileage too !! 123k

[@wysetech2000]

Well done,James and a little humor helps too.

[@jamesdanner7850]

+wysetech2000 thanks. We like to have fun

[@arthurfricchione8119]

Good video. Like how you checked for leaks using compressed air and not a smoke machine. Guess you don't need all that fancy stuff. Just go old school. Are you related to scanner danner? Like your videos

[@jamesdanner7850]

+Arthur Fricchione thanks. Fancy stuff can be cool but I AM a little old school. HA ..Yea Paul is my brother.

[@PineHollowAutoDiagnostics]

"We'll call it diagnosed and NOT fixed" haha that was too funny James. Good find. I thought Honda engines were supposed to be more reliable than that?

[@alexp1357]

This is the bad gas issue, not Honda.

[@CharlieKim]

The engines on these are fine minus the hate. The transmissions attached to these however were trash....

[@Jpilgrim30]

Charlie Kim I can agree with that. Just flipped one of these someone was selling because of a junk transmission.

[@792bnz]

@Wildman whats wrong with the design?

[@timguy161]

To work on Bank 2 valves, no need to touch intake air manifold. One KZbin video shows that. Not so for Bank 1.

[@mattanderson1831]

If you had to guess, what would you think caused this on a low mile car? Just a manufacturing defect. Anyways, great vid

[@jamesbuttery3862]

Detonation.

[@glasser2819]

misfires... crappy iridium plugs! Replace with double platinum no more misfire 😊

[@MrJolppy]

Mine had the exact same thing happen I just drove it until it blew up

[@SxyN8]

How did that work out?? Planning on doing the same thing

[@psicopatalucifer]

Nice video , thanks for post it .!

[@Desertduleler_88]

Did the reduced tappet clearances burn the valve out?

[@Aristotle2000]

I wonder if the valve got damaged during the timing belt change on the interference engine. Hmmmm...

[@woppini]

Aristotle2000 Probably burned since the valves run too tight as the miles pile up.

[@Aristotle2000]

I see. Thanks.

[@jamesdanner7850]

+Aristotle2000 any of us who do timing belts alot have that story where the cam rotated and clunked. Eek. And u wonder if any damage got done. This belt was done probably 15000 miles before this happened. There was alot of carbon in the chambers. Honestly not sure if something held the valve open slightly long enough to burn it or it did have some detonation or ping.but he only pulled the one head. ,bought a valve on ebay or something . Drove it a few weeks til wife's new rav4 was ready . And I think it had a momentary misfire on one of the rear bank cylinders that went away. Makes me wonder if there are valve guide issues where they are too tight and start binding ? I have no good answer

[@andrewwmacfadyen6958]

Eric O at SMA had a major valve job on a Honda V6 a couple of months back --- valves just one bank of cylinders.

[@Force1Com]

@@woppini How could the valves be tight if they weren't tight when he checked the valve lash?

[@alexp1357]

Guys, this is your job to find the issue, non the owners'. Dislike for your investigation.

[@LukeJones29]

I heard if you get the ecm updated at a honda dealership it fixes a p2195 issue

[@LukeJones29]

This true?

[@glenharper3136]

About time James.

[@Wrenchlife604]

What do u think caused the exh. Valve to burn up prematureley

[@jamesbuttery3862]

Detonation.

[@glasser2819]

tight lash opened made it too hot for too long ✌️

[@BigMac2222]

The Vtec didn't kick in, it kicked ass.

[@aussiebloke609]

Nice work! I had a valve get badly burned once, back around '90...just got the car back from a service and the valve clearances were too tight. It was about then that I started really working on my own car. :-P Btw, I just found your channel, and subbed - now, to go back and check out all your old vids. You can blame your brother. :-P

[@mikeanderson1994]

how much dose it cost to fix i have the same problem on a gm chevy caprice 305 engine the heads must come off but i want to know how much will it cost me thanks

[@baxrok2.]

Uhm, yeah, but where's that chunk of missing valve!? Yikes. Nice job James. Thanks!

[@jamesbuttery3862]

It was exhaust. Probably sucked out the tailpipe.

[@baxrok2.]

Well, at least to the catalytic converter honeycomb where it eventually got slowly vaporized/melted!

[@jamesbuttery3862]

Righty-O

[@SonomaLow12]

Wondering if anyone can help me with my frustrating misfire in my 2008 acura 3.5l v6 172k. It only misfires when cold or sitting for a lil while. When it misfires it only lasts for 5 to 15 seconds then goes away. Things iv done: replaced all the spark plugs and coils. Replaced all the fuel injectors and did a valve adjustment. Cleaned egr and intake manifold. Put in new pcv valve and map sensor. Sometimes it will throw random misfire p0300 or just a #5 cly. misfire. Then some days it wont misfire at all. Im lost. Please help!!!!

[@jamesdanner7850]

Are u using coolant? Sounds like some head gasket issues I've seen where it seeps coolant into cylinder while cooling down . And itll misfire til the coolant is burned up and cleared from cylinder. I've proved this by pulling the plug on suspect cylinder and put a pressure tester on radiator and look down plug hole after time elapses.

[@SonomaLow12]

@@jamesdanner7850 Did the radiator pressure test already..was good. I'm leaning towards a ripped spark plug tube seal I recently replaced. I'm getting some oil in the #2 CYL. I'm really hoping thats it. Tired of this chit. Ty for the reply!

[@JohnDoe-ek7ic]

I’m currently having the same problem I changed plugs coils intake gaskets valve adjustment

[@JohnDoe-ek7ic]

Also losing coolant slowly

[@drtokubuns]

Did you ever fix this?

[@uzochukwuvictor5102]

Which is the best oil for Honda

[@tecnaman9097]

Your scanner read the misfire counts but Nick's didn't. Mr Snap On man please explain?

[@jamesdanner7850]

+tecnaman not sure. I did mention that I actually punched in an 03 in his scanner and it's an 04 and his was way back oin updates. but now we are both updated to 17.2

[@SxyN8]

What's that, Baltimore??

[@somerandomguy3868]

was that valve broken? how does that happen? wtf great video you get some strange stuff roll into your shop

[@halleffect1]

you said exh valve clearance was ok, i wonder what made the valve burn?

[@jamesdanner7850]

+halleffect1 it's only speculation but some were suggesting detonation from like cheap gas. Or if any of that excessive carbon in the first picture started glowing hot and ignited the fuel mix too soon so 2 flame fronts collided or it just flaked off and held the valve open a little.

[@halleffect1]

i'd go with the carbon hanging the valve theory.

[@zheloshuvieraheshadonelkhu1874]

A valve adjustment to a cylinder with 1psi of .... doesn't make sense..

[@tagperformance]

bent valves due to incorrect timing. Customer did the timing belt prior to having misfire issues.

[@rhkips]

"Is #3 still unplugged, Nick?!" This is just about the best way ever to get someone to zap themselves on camera. Shame it's Coil on Plug... LOL That exhaust valve wasn't broken, it's just one of those new-fangled low pumping resistance fuel economy valves! ;D

[@jamesdanner7850]

+rhkips oh. Maybe that's how the vtec works.:P

[@rhkips]

Haha, I think in this case, the VTEC fell out!

[@MichaelMcNeilg]

You guys are funny more videos please :)

[@R.E.HILL_]

You are very interesting and enjoyable to listen to. However your camera work... I wish you would put more of an effort into it. Keep sharing, very much appreciated.

[@jamesdanner7850]

+R. E. Hill thanks. It's harder to do than I'd like given the small windows of time I have to film at a working shop. Was thinking about some wide angle glasses to try to get more content and see how it works

[@R.E.HILL_]

James Danner Eric O camera work is something to look at. he is suprisingly good. his use of a tripod small and big, on wheels or not(is he using the gearbox jack? ☺). when you walk around with the camera I get seasick. I watch it anyway... ☺
