97 Cavalier 2.2 - Rough Idle
I need some help. I have a 97 Cavalier 2.2L. My car started smelling like gas inside so I took it into the shop and they replaced the Injector O-Rings and 1 of the Injectors that was bad. The gas smell went away but after all of that then the car started to idle badly when at a stop or the car is in park and shakes. When I take off sometimes it is like it wants to stall out and die but it doesnt. The car has died twice but hasent died in quit some time now. I have replaced the plugs, plug wires, 1 injector (mechanic said the rest was fine), all the injector O-Rings, Fuel Filter, and map sensor. When the car is actually driving it drives fine and it drives smooth.
Oh and also if I have the A/C running then the car stops shaking and seems like it is idling fine. Not always will it do this but for the most part it does while the A/C is on.. Would anybody know what could possibly be causing this? I've been told by somebody else that they think it is my throttle body. Anybody else agree?? Trying to get some suggestions on what it could be. Please let me know. Thanks

Re: 97 Cavalier 2.2 - Rough Idle
I personally have had replacement injectors that flow at a different rate than the OEMs While the sequential fuel injection should be able to compensate to some extent for minor injector differences, significant differences in flow rates can cause exactly what you describe. It's usually best to either replace entire sets, or have the injectors tested and flow-matched. There are several services nationwide which perform this at a minimal cost, under $15 per injector.

Could somebody tell me where the "IAC The idle sensor" is located at on the vehicle? I know where the TPS sensor is located but not the IAC.
