I agree with greg's,If the vehicle is equipped with an electronic throttle body what happens is the computer will compensate for any carbon buildup on the throttle body by holding it open passed this point,so when you take the memory away by removing the battery it wipes this predetermined value away and the idle quality suffers.The easiest thing to try is just cleaning the throttle body and then drive it.
you might have to reset security system
Need to have alternator checked as well.
