running like crap!

jacksmiles · 04-18-2005

my 95 gt with a vortech supercharger is running like crap. at first i thought it was the o2 sensors but i replaced those and nothing. i was running rich before that and fouled the plugs so i changed those and nothing. fuel pressure is only at 38 psi so how could it run rich. im only runnin 6-7 pounds of boost and it just runs like there is a miss in it and stutters. what could the problem be. please help me.

check your tps voltage

You never know truely what it could be but,I think it
could be your EGR,IAC,or very possibly your spark plug
wires.Do you have a check engine light on? I would have
your car looked at to know for sure.

If you are still running the Factory emu program that could be the problem. I had a similar problem on my 96GT when I added a Procharger w aftercooler. I also changed the injectors to 24psi. Ran rich until I flashed a new program. I'd have someone with an OBD reader check the codes. You may need a new chip or a flash program.

clean your mafs with some contact cleaner. that's what fixed my problem. also, if that doesn't work, check your base timing
