First thing in morning when starting cranks just fine but for a long time when it does start surges goes away when warmed up.
Also check the fitvalve... may need opening and cleaning the spring mechanism
Check the idle position sensor and clean the idle control valve. to clean the IAC, spray some brake cleaner directly at the valve after removing the air cleaner duct work. Do this with the engine running at 1500 rpms.If the valve is dirty it will clear up.
Get a scancode to check the sensors. it would be a good idea even before cleaning the IAC valve.They do it free at autoparts stores.
