If your not talking about when the engine is cold and the Autochoke is engaged...

A searching idle can be various issues...but first i would look into these

IACV (Idle Air Control Valve) or the FITV (Fast Idle Thermo Valve) these can cause a "roaming/unstable idle"..

Here are some good links on how to clean them ;)

GSI_PSI if your car is always on the C on your temp gauge your t/stat is probably stuffed
