Sounds like it could be a problem in the IAC circuit. The Idle Air Control valve manages how much air gets into the engine while @ idle. It receives commands from the ECM based on inputs from at least the mass air flow, coolant temp, throttle position and oxygen sensors

Might just be the timing is off a bit, turn your distributor or if it has a carburator, the choke might need to be turned up.
