Engine Problem

GR33NMACH1N3 · 09-15-2014, 09:54 PM

I have a 2007 335i with 100k highway miles.
I was parking my car last night and got a service engine code and it started to idle really rough. I scanned the codes and it said misfire in cyl 3 4 and 5. I replaced all 6 spark plugs today and not I have a p1554 code. The car will drive good for about a minute and then the service engine light will come on and idle rough. Any Ideas? I will clean out the VANOS solenoid tomorrow and change the oil. Thanks

What about the coil packs ? They are not suppose to last that long. I will assume that that it is cylinder 3 that is misfiring and causing the next two (4-5) to have an issue. Just buy all 6 coils from autohausaz.com ( $40each)

Like MPoster said, it could be coils, but you do need to know the codes.

could be injectors, but check the cheap stuff first as it is more than likely a coil pack.

I'm pretty sure it's your dme injector mosfets went bad.

This is a possibility, as others have notes pull some codes first to see what's really going on.

It is probably a bad coil or coils

check your coils, my friend had the same issue,when obi connected it shows misfire in cylinders, he changed coils and everything was fine.

Found the problem. Cleaned out the solenoids and changed the oil! Thanks guys!

Out of curiosity ... stock turbos ? 100k miles ? Are you tuned?

I agree....change your coils dude. I also feel your fuel pump is going. This many misfires in this many cylinders sounds fuel deficient. Any knock sensor codes by chance?
