I'm going to describe exactly whats going on and everything I've tried to do to make this easier.
When I'm at a dead stop for about 5 seconds I'd say, when i go to take off, low throttle, slipping the clutch, the car with buck and bog and go super lean on me. (my wideband pegs on lean) Then after about 2 seconds of running like an absolute DOG the wideband comes back into the "stoich" range and car runs fine.
RPM is around 700-760 When its warm
My Fuel Pressure is set to 43.5psi with the vacuum line off (I also used pipe sealer on it so it would not leak, but when I connect vacuum it drops about 8-9psi, is that correct?)
Boost gauge is reading vacuum of 15-16psi (isn't that low?)
I have my SAFC set to -19% across the board with it at 16 at 1000rpm
(I have tried setting from -10 to -20% and no change with the problem I'm encountering )
I did a boost leak test , and discovered one major leak in the j-pipe it had a hole in it. And my Idle control stepper, one of the o rings went bad and was leaking seriously. So I fixed both of those expecting this was the culprit of this problem. Boost leak tested at 15psi, NO leaks that I found. If I let off the compressor the PSI will drop about 1 psi every 3-4 seconds.
My last thought is that possibly the ignition timing is off? But I can't find how to check or adjust it anywhere.
Could bad injectors be a culprit of this? It all started when i put them in. I thought possibly it was just that I couldn't tune but at this point I've ruled everything else out.
Oh last thing when I FIRST start the car, hot or cold, it runs fine for about 2min then runs like DOG at low throttle like I explained.
Help guys, id really appreicate it, im so lost.
If worse comes to worse ill meet somebody to diagnose this stupid thing, ill even throw you some cash if we figure it out =)
