I noticed since my car engine had replaced cylinder head gasket kit it drops the RPM while the engine is cold. After 10 minutes it will go back to normal RPM. Wuold you please tell me what might be the problem. I replaced the Spark Plug, and Ignition coil but it looks like Iwas spending money with out improvements. I applied injector cleaner but still thesame. Please advise

Hi placidii,

Seems the IAC is not working correctly or the valve clearances are too tight.

Get the throttle body and IAC cleaned and see if it helps. Readjust the valve clearances.
