Ok well i got my NOS Kit in yesterday. The car runs fine on spray but it idle is messed up. Ok heres what its doing, You crank up the car the idle shoots up to 2000rpm, You rev it a few times it goes down to like 1500rpm. Then you can from inside the car pull up on the gas pedle and it will surge a few times then level out at around 1200rpm. My NOS Kit has a WOT Switch. You have to cut the TPS harniss ans run it thro this box and wire the TPS plug on the other side of the box then plug it back into the TPS Sensor. It didnt do this befor and im not sure why its going it now. So any and all help is awsome.
Did you check to make sure your TPS is still within spec?
Im about to go do that now.
make sure the throttle cable is not too tight. Also, triple check the wiring you did when you did the install.
