Cylinder 5 misfires on heavy load, swapped ignition coils, swapped spark plugs, swapped injectors, checked for continuity in ignition coil connector, measured voltage in coil connector, adjusted valves, did cylinder leakdown and compression test, swapped pcm....What could the problem be?

 

no suggestions?

 

Sounds like you have tried just about everything. Possible problem with the EGR system?

 

Does this engine have variable cylinder management?

 

yes, we've tried about everything. we just did the fuel pressure check. went for a test drive and did a snap shot of the system. i guess we gotta call the professional honda-techs up

 

You mean Tech Line? LOL, theyre just going to use you for R&D. I bet you one of the rockers on the 'dead' bank of cylinders is whats giving you trouble.

 

it has vcm but supposively it only affects bank2 and not 1. btw i work at honda and we're trying to figure it out. all the techs bust my ***** for coming on here and i just wanted to see what your opinions on this was. thanks a lot

 

tech line said to keep checking crap, worn cam lobe, crankshaft end play, etc. hmmm

What did i tell ya! R&D!

 

yeah, thanks for your input. you proved to some of the techs here theres people out there on this forum with knowledge other than what springs should i get for my car or what intake is best haha

 

we figured it out....Cam Lobe was shot! it worn down about a 1/4 of an inch. pretty crazy

 

Now to figure out why that lobe took a ****.

 

Ill have to remember this post in case this becomes more of a problem. TIA.

Gotta love warranty work!

 

haha yeah warranty work ftw

 

Did compression readings differ with worn cam lobe?

 

no it did not. after clearing the mil the only time the mil would come back on was under heavy load/full throttle.
