Re: ***How-To Clean*** Your IACV a.k.a. Idle Air Control Valve
Question with iac valve.... I have a 97 civic with fluctuating idol... Whenever I tap on it the idol goes back to normal temporarily... Is it save to say that it's the cause of my symptoms?

Could someone please confirm if this is the Idle Air Control Valve on my 01 Civic? thanks

Question on this process, I've got a 1995 Acura Integra and am wondering, if I don't have any idle issues as listed in the OP, should I go through this anyway? The car has about 218K on it but I've never had any kind of hunting/rough idling.

Re: ***How-To Clean*** Your IACV a.k.a. Idle Air Control Valve
so i cleaned my iacv and put it back on gaskets there ever thing looks in order but still has an idle surge i took a can of brake cleaner to see if maybe there is another exhaust leak and when i didnt find another leak i sprayed my iacv again and the cleaner bogged the engine after spraying it im thinking maybe i need another gasket? maybe its warped?? any thoughts.

Re: ***How-To Clean*** Your IACV a.k.a. Idle Air Control Valve (howard-zhang)
hey guys--i just solved the problem w/ my 94 GS-R dropping idle to 500rpms/dimming headlights and eventually dying on me while at idle at a stop after my vehicle has been warmed up to operating temps. i solved this problem by cleaning out these three components: IACV, FITV, and throttle body butterfly. the problem now is that i have coolant leaking from my IACV...i believe its leaking from the bottom square plate w/ 2 bolts that covers a thin gasket in a narrow groove. i tried purchasing this gasket at the dealer but, they say that's not a serviceable part so they don't selll it! i wanted to see if anyone has a similar problem and what did you do to solve your coolant leak? i was thinking i could make my own gasket w/ some permatex gasket maker or does anybody know if i can order this gasket online or if there is an aftermarket gasket available? any help or information would be much appreciated...
howard: i would check and clean out your FITV if your experiencing idle flucuations as this part controls your idle speed after startup and when your englne is cold then switches over to the IACV after your car has reached operating temps. to control idle when at a stop.
thank you.

This is the only time it makes sense! I have seen some guys clean it only to have a idle issue after and sometimes still have it so unless its easy to access or you have symptoms leave it be.

I know this is an old thread, but if the user is still around and still has the pics, can you redo the pics so we can see them?
They are currently stored in Photobucket, so are blurred by Photobucket, meaning users of this thread on how to clean an IACV cannot see the pics.
We would have access to clean pics if we get an annual prescription to Photobucket (I believe currently at $99 per year), which I think many users would be averse to.

Re: (PatrickGSR94)
The IACV motor shaft runs thru the IACV and rotates the shaft according to the idle air flow needed to maintain proper rpm's. The shaft has a metal mass which rotates according to the magnetic field applied by the electromagnet stator and varies according to the voltage applied to the stator, which rapidly opens and closes the intake air passage according to idle air needed. What often happens is the shaft gets dirty and the shaft rotation is obstructed. It must be cleaned so that the shaft rotates freely with little to no binding. Usually the shaft must come out and a long duration lubricant sparingly applied.
