When battery is disconnected, it would lose all memories and the computer would need to relearn. Go for a drive and be gentle and gradual with the accelerator. The problem would sort itself out after a short while as the computer relearns.
Cleaning the throttle body and ISC would be a good idea as the idling speed is low indicating they are dirty.
