My car will start and run fine until I come to a stop or a red light. If I turn the air conditioner on it will roughly idle and won't shut off at a stop.

It sounds like you have a vacuum leak, or the throttle body needs to be serviced.

Here are three guides to help us fix the problem:

and

and this guide is only used when the engine is cold.

Please go over these guides and get back to us.
