My air-condition system would turn on randomly sometimes. It stopped doing that, but now if I turn on the AC, turn the car off then turn it back on later could be an hour, two hours or three the car would start fine, idle fine then shuts off suddenly.

Hello,

It could be that the air conditioner is heating the engine up a bit and causing the crankshaft angle sensor to go out. Here are a few guides to show you what you are in for when doing the job with some diagrams (below) that will show you how to change it on your car.

you will need to jack the car up because it is near the bottom of the bell housing (below).

Also, you should run the codes.

Please let us know what happens.
