Engine Stalls only when AC is on

2001 Sebring LXi Coupe, V-6 3Litre, Manual 5 spd, 140,000kms.

Battery died this week. Disconnected terminals and replaced. Prior to battery failure, engine ran great.

After battery replacement the engine would stall when coming to a stop. Thought that maybe it takes some driving to reprogram the onboard computer.

And yes, now the idle is OK(800rpm @ idle).

PROBLEM is that if the AC is on when coming to a stop, the RPM's drop to below 500, and the engine stalls. If I shut off the AC prior to stopping, idle is good, no stall. If I am sitting at a standstill, turn on the AC, the idle will drop, and stall occurs.

Thinking it may be Idle Speed Control Actuator, and possible a few other sensors & controls.

What is unusual is that it all started after battery change.

ANY THOUGHTS!
