so i took of my IACV and clean it out but, my car is still surgin rapidly from 1500 rpms to 5 or 400 rpms... when i took it of it didnt have the round gasket on it but i took it of my old head that had a manifold on it to put on my skunk 2 manifold on my type r head.... but it didnt have the gasket b4 and it worked fine.... this whole problem started after i put my new head on... any1 got any other ideas???

 

Try cleaning ur FITV, do a search if u want to know how to clean it. It's the fast idle thermo valve located on the throttle body.

 

Vacuum leak or wiring issue. Cover the 2 holes on the throttle body and if the car doesn't die then its a vacuum leak. Unplug the IACV and see where the baseline idle is set.

ill try it and let ya know asap!!! thanx

 

I had loads of idle surging last year when put in a jrsc. My tuner tried configing my hondata, but what really worked was unscrewing the idle screw on the throttle body. He unscrewed it A LOT (not just a couple turns, ALOT of turns) but he told me if the idle started going back to surging, then its time for a new IACV. So, it fixed the problem and my idle didnt fall below 1K rpms, until recently. Now im biting the bullet and getting a new IACV, should be in this week, ill reply how my idle is after.

 

sounds good let me no the results!!!

 

btw, kill the bold.

 

Try the IACV, if that doesn't work, punch your car right in the taint
