when my car warms up the idle is off by far. i read something about cleaning the iacv it out with some break cleaner, i tried that today and my idle still goes up and down pretty bad. before i go drop some money into another one is there anything i can do or is there anything else i can check out before hand?

the idle bounces up and down? or it is just low?

 

it bounces up and down

 

another thing is that the engine is jdm. does that matter if i have to buy a new iacv or can i just get one for any h22?

find the fast idle thermo valve underneath the throttle body...it has a flat plate with two screws...take off the plate....there is a collar/screw with two notches on either side...use a screwdriver in those notches and tighten it all the way...then back it off a full turn.
