fitv valve. its located under the inlet manifold.

remove the 2 screws.
turn the collar clockwise till its tight. but not too tight its made of plastic.

mine did the same as yours, and this is what i found fixed mine.

I found mine was fixed by adjusting the idle speed screw down ever so slightly, only knocked around 50rpm off idle speed, but cured the hunting problem.

Put your thumb over the lower big hole in the throttle body before doing what Honda-hardy suggested to establish whether it's the FITV or not. If the idling sorts itself out when you cover it then do as Sam suggests. Otherwise have you removed and cleaned either the IACV (Idle air control valve on the front of the intake manifold, or the EGR valve?

Thanks guys, means alot that your trying to help, forgot to mention that ive already taken the idle controll valve off and its clean inside nothing seems wrong in there,

Air leak into inlet manifold. Vacum pipe leak. hole in downpipe, especially near o2 sensor (i had hunting caused by this)
