My car is having similar symptoms as flywright64 but I didn't want to highjack his thread. You all helped me to get my ac problems solved and now I got a PO 117 code according to my scanner. This has something to do with a fault in the temperature sensor I believe.

Prior to the scan, the tack went down to 500 and then the car stalled for the first time today. I was turning into a parking lot at the time and so pushed it into a space. It would not start back up until I let it cool for about 5 minutes and then within a minute it would stall again.

On Friday and Saturday, for the very first time the temperature gauge fluctuated close to the red and 10 seconds later returned to the 3 o'clock position. So it was acting strange before the stall today.

The cooling fan was on even after shutdown but did stop in a minute. Is the temperature sensor telling the engine to shut down because it falsely measures that the temerature is too hight? The sensor also had a drop of dried antifreeze in the middle of it where the wires are. Is this my problem?
Thanks,
George
