When a car won't idle, it's almost always a vacuum leak. There is a fuse that feeds the a/c compressor, that if it's blown, the car won't idle, but that's very rare. Take the car to someone who's more qualified than you are. He might find the vacuum leak.

i checked all the vacume lines, the ac fuse, but what about the idle air control valve?
