2003 PT, 4cl, 74,000 miles. Car Idles rough with the AC on, almost wanting to shut off. The past 3 times when I have put it in reverse it has died. I would just like to learn more about the car I am always putting money in. Thank you : )
Lets start by checking up on the IACV ( idle air control valve ) this is the one that suppose to maintain the idle. The computer when it gets a signal from the AC that the compressor is On-the computer turns around and tell the IACV to raise the idle due to the AC load on the engine.
