CAR STALLS IN REVERSE AND RUNS ROUGH WITH AC

Chrysler PT Cruiser

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.
