check the Idle control motor if ur car has one which it should.(i think) if it doesn it is called the IAC then.

is it fuel injected engine(im guessing it is) i got a 91 sunbird and it has carberator on it. so im not quite sure where it would be so i would take a guess http://www.autozone.com/servlet/UiBr...NENT+LOCATIONS

IDLE AIR CONTROL VALVE
On your 1996 PONTIAC SUNFIRE, the IDLE AIR CONTROL VALVE is:
UNDER HOOD, CENTER, REAR ENGINE AREA, FRONT OF AIR INTAKE DUCT, MOUNTED ON FRONT OF THROTTLE VALVE ASSEMBLY

Carburetor equipped J bodies disappeared after 1982.What might look like a carburetor is actually throttle body fuel injection.The fuel pump is in the gas tank,not mechanical on the engine block.Later J bodies went to MPI,and then SFI.
