idle control problem

hey... I have a 96 sunfire 2.2L and my motor is reving up and down constantly. I Have Been told that it could be a whole bunch of sensors.then this one guy told me that it was my car's computer...could it be the computer???? Thanks...

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

thank you...

i have another question, recently over the past few months it takes my car a long time to heat up...it takes something like close to and hour to get to normal range...can anybody help me out please??.....Thanks...(96 Sunfire)...oh and where would the iac be located to on my 2.2 sunfire???

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/UiBroker?UseCase=C002&UserAction=initiateAlphaSearch&Parameters=%7C%7EI%7C%7ECOMPONENT+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.
