Faulty engine temperature sensor ?? On a cold start the temperature sensor should detect a cold engine and give a signal to the ecu to increase fuel ratio until the engine has warmed up. sounds like faulty sensor to me.

The Idle Air Control Valve (IACV) may need cleaning or replacement.

This valve lets air bypass the throttle plate so that the engine can idle. The more air, the faster the idle. If this valve is sticky, the computer may have a hard time regulating the idle properly and may surge.

Cold Start Idle Issue


Problem might be the air control valve, it's located at the right side rear of intake manifold and has a hose going to the air intake duct from the air cleaner, as a test you might try pinching off that hose when the idle is a problem.
