Basically pull the negative battery cable, then hook it back up and start the car. Put it in neutral (park for an auto) with the parking brake set and let it idle up to operating temp. Once it's at operating temp let it idle for at least one full minute with all accessories off, then at least one more full minute with the AC on. Drive the car for at least ten miles before shutting it off and this should let the ECM relearn the idle and fuel trim strategy which usually fixes things like a rough idle, stalling, bucking, etc.
