Possibly idle air control valve.

There is an idle speed up device to compensate for the added load of the air conditioning compressor. When you switch on the air conditioning an "A/C request signal" is sent to the PCM (powertrain control module). The PCM then increases the idle speed about 50 RPMs & engages the air conditioning compressor. If the compressor is actually coming on, sounds like it is, I'd suspect the IAC (idle air control valve) is not responding to the small increase in idle speed request. Could be dirty & sticking.
