i installed the zzp SC kit and now when i start the car it hesitates when i try to step on gas even lightly.noticed the problem goes away when it warms up.

it almost feels like the car is shutting off, no jerking or chocking noises

vac lines all ok, intake is plugged in rite..

any one have a clue?

could it be the pcm?

 

it does it when its in park as well.

 

do you still have the factory pcm?
and if you do...did you have it tuned for the supercharger?

 

nope i got a tuned one with a SC kit from zzp i was speaking to them and they said i need a new one and were going to replace it under warranty

 

Could also just be the IAC, but the tune might be choking the car until it's warmed up. When it is warmed up then the oxygen sensor starts to talk to the PCM and adjust the air/fuel ratio. When the car isn't up to temp, the PCM just dumps the maximum amount of fuel
