Hi dr09q,
If the idling speed is low with AC compressor running, the engine would want to stall abd when engine speed is too low, the compressor would be turned off. This repeated cycle would result in the engine idling go down very low till engine feels like stalling and then back on again.
Get the throttle body and IAC valve cleaned and problem should be over.
