so i developed a problem with my car and i have not been able to figure it out myself and nothing has been helpful from other sites so i figured i'd try my luck with the SVTP Gods.
the car: 2002 GT with a 1998 lincoln mark VIII motor swap. cobra upper/lower intake, imrc deletes and some other minor things (shorty headers, 03 cobra maf, 24lb injectors)
what it does: it is most prominent at idle. it will be rough and my vacuum will drop off slightly (normally -20in/hg is good but i will pull like -17~ish or so when it starts acting up) on my sct, my fuel trims are way out of wack from one side to the next. short terms are like .98 for one side and the other will be way up to like 1.25. the only code i pull is a P1152. my O2 sensors are new (motorcraft replacements so they are OEM pieces) so i fugure that isnt the issue. my fuel pressure hold steadyr at 40psi so i dont believe its a delivery problem.
so what could cause this ??? it seems to come on at random times because every once in a while it will sit right at -20 and idle just fine (it doesnt happen often but sometimes it will) i'm assuming its something to do with the passenger side bank but i'm comming short on ideas of what to look for.
any help?!?!
thanks guys!
