    When the battery is disconnected, the PCM loses idle memory. It can relearn, if the throttle body is clean. If the throttle body is dirty, it may not. Try cleaning the throttle body and disconnect the battery again. When finished let it idle two minutes in park, without the AC on. Next turn the AC on and let it idle for two minutes. Lastly, put it in gear, with your foot on the brake for two minutes. It should relearn and be fine. Here's more information on idle memory.

    Good Luck
