I'm assuing the missfires are caused by the dead O2 sensor eh?

could be.....or are all three of those cyl. ran off the same ing. amplifier?

Hmmm.... Good observation... I'll go do the old, unplug and replug trick...

missfires in 5 and 6 are attributable to the issues in 4. What are the missfire counts on 4,5 and 6?

reefer_bob

I havent' logged it yet cause I just seperated a tire... that's just from the codes.

This fvcking thing is like a virus and it's super contagious. If you're reading this thread, immediately inject your car with 100 octane before it's too late. Just reading this thread could be detrimental to your S.

It seems to only infect 4,5,6. I had the disease for awhile but fixed it with a new spider and/or new injectors and/or driver's side EGT. I got them all done at ~the same time so I can't be certain but I know first hand of people that have done everything including changing out the head with ZERO improvement.

The misfires occured in mostly 4 @ ~1 p/s while misfiring in 5,6 only slightly less. Misfires slightly improved when clutch was engaged but only momentarily. Misfires also occured when slowly rolling to a stop.

****, I'm still getting them in 4,5,6.. just not as bad. But I must say that it's one of the main reasons for my recent interest in Airbox mod testing.

I'm sorry man but I'm sure your's will be easily fixed with a simple O2 swap.

lemme know if you decide on new O2 sensors. OT, what are your plans for clutch?

reefer_bob

I will keep you updated. It's never done this before, so I suspect an O2 is to blame...

reefer_bob

Yep. Not sure on clutch yet. I'm leaning clutchmasters though.
