Well just for kicks I had the alternator tested and it was fine. The IAC I installed was from rockauto, might swing by the dealership tomorrow and get one from them. The jeep will idle but only when the engine is cold. Does this sound like what a bad IAC might do? Runs fine driving down the road but I did notice that if I let off the gas the RPMs drop right down and as I slow down the jeep will eventually die. Does anyone know how to check and see if its a bad PCM?

Don't wanna sound stupid but are those complicated to operate? I really don't know much when it comes to electrical stuff. Is there a DMM to avoid? Features to look for? Like I said I'm not good with electrical.
Cheap ones work fine for occasional use.
