How about the alternator? Any shop can check it for you. If an alternator is going bad it may not crank out enough amperage to support the car at idle, hence the rough running or even stalling. Even with a perfect battery this can happen. This happened to my wife's escalade while we were moving across country - the extra load on the air shocks while towing tipped the balance and if she slowed below 1500rpm the car would stall. We even bought a new battery on the road...it bought us a few hundred miles and then she stalled. We were able to limp along and finally made it - new alternator a week later (along with the leaking air struts that caused the demand) and problem solved.

It very well may not be this, but I would at least check this before dropping the engine.
