Check alternator output. It should be around 14V when the engine is first started and then settle down to a bit over 12V in 15 minutes or so of driving.

Pull out your IAC. Retract the spring and screw the pintle in several turns. Replace it and see what happens.

Try cleaning out your throttle body and what phonedawgz said also. When battery is disconnected computer might have to go thru a relearn.
