Default Car shuts off

Hey guys,

Got the problem fixed with the car wanting to studder when cold, it was the o2 sensors. But now I have another problem to fix (it did not just start...) Every since the blower install, my car wants to shut off if I am in 5th, 4th, and sometimes 3rd and I press the clutch or put it in nuetral. If it does not shut off, the rpms will bounce and eventually shut off. My timing drops to about 8* at idle when this happens. If my car is sitting still, it sits fine (but an occassional rpm bounce). What could cause this? Vaccuum leak?

Stock engine with a KB S/C on it, KB boost-a-pump, KB intercooler. Brisk spark plugs, bassani o/r x-pipe, flowmaster mufflers, 4.10 gears, and that's basically it

I have a fuel pressure gauge in the engine compartment. The interior ones have not been installed yet (working on getting everything running perfect first). It tops out at 10 psi boost (this was from the dyno)

ok, i feel like a broken record....

what about the throttle body, have you
ever cleaned it....perhaps that is all it is.

there have been some recent threads about
poor idling and such and cleaning the TB
sometimes makes a world of difference

Sounds like a bad tune maybe.? My car ran great with the first tune until the outside temp dropped from 105 to about 85-90 then the car ran extremely rich, had a little trouble starting, would bog down at light and almost stall, even at WOT the car sounded like it was bogging down. You may want to put the car on the dyno, check the A/F you probably have some spikes and dips in the curve.

It's been on the dyno a good amount of times. The A/F seems to be fine all throughout. I will try cleaning the TB.

Mike Ward Racing did the install initially, but we had problems with him. Took too much time, had too many problems, and charged me for things I didn't need/didn't want and for parts that he didn't even put on. I have it at a new guy now, Dyno Tune Motorsports, and we are trying to fix all the problems that we initially had.

BTW, last night I did get error code P0191. Haven't checked if it's still on today.
