Sticking or dirty air control valve. Remove and clean.

Make sure your radiator is blead. If there are any air pockets it can cause a fluctuating idle.

Well HONDA-TECH you have saved my *** again. i cleaned and adjusted what i think is the idle air control, but what ever you called it, it worked. But there is a problem with running lean when im just at a steady speed. do you have any ideas on this problem. plus what kind of cars you all got.

Either fix or ditch the FITV.
