Message ok so here is the rundown:
Finished my TT swap on my 2+2 a few weeks ago and had so many problems along he way but i am a determined person so i got through it. Started her up and she was pretty strong with the exception that when i let off the gas the car would stall out. It held like a 900rpm idle but after a bit of light reving to 3k rpm and let off the car would not catch and stall right away. I can tell you i just recently replaced 2 coils because i did a power balance test and two were dead on cylinders 5, and 6. The injectors are clicking and i am 99% positive i connected them in the correct firing order because i went according to a color coded ECCS diagram i found here on the forums. Its misfiring like a bitch the whole car shakes and the idle has become erratic after only driving for 4 mile intermittently. there are two small leaks on each side of the motor i think from the returns on each turbos. probably due to a mildly loose clamp not a big issue. Ptu is ok and cas is set to 15 degrees BTDC. I am pulling my hair out trying to figure this out and my vacuum is good on my gauge. oil pressure is like 30lbs at idle and fuel pressure is at like 45 or 50psi. the car wreaks of fuel. and i have no leaks due to having a 100% SS setup for my ful system with nismo 740s that were bought brand new. I also have a chipped ecu from ash according to my build and a selin translator on the correct setting of AVG for dual pop. Can someone point me in the right direction to my misfiring. The injectors all click normally. te tps is not set 100% correct but its close enough to where thats not the reason for all this mess. I did not regap my plugs when i got them from Z1 so could those be my problem? Any help is much appreciated, please help me wrap my build up.
-Brian
