sounds like you have a short... is it a stumble to a engine shut off or is it instantly?

It happens when i slow down to a stop.If im on the highway at cruising speed and shuts off the A/C,it will continue to run,but if i slow down to like 10-5 mph it shuts off.I put it in neutral turn the key and starts rite back up.

Sounds like the IACV or even the MAF is shot. The IACV controls your idle speed. When things are turned on like your lights, radio, A/C, etc, the throttle opens a touch more to allow air. If the accessories are turned off, it closes up a touch. If your IACV is dirty or even malfunctioning, it literally chokes your car. You can clean the IACV by removing it, cleaning with Q-Tips and rags, then reinstall it. You might want to clean your TB a bit as well. Now, if it's your MAF, the car will die in a similar fashion. However, a MAF error will create a CEL light. I would check your codes at that point to see what it's telling you. I don't know what year your car is, but you can hook up a OBD2 scanner on vehicles 96+. If it's a 95 and older, you can actually get the codes with a paper clip. Do a search on these forums for the appropriate way to read codes on an OBD1 car. If you need help locating your IACV, let me know.
