IACV help
I just got a brand new IACV and after I installed it, it started to make a loud clicking noise every second. I called up the dealership from where I bought it and he told me that I have to reset it for it to learn the engine. However he does not know him self how to do that. Can someone who replaced their unit tell me what they did.

The valve learns nothing.
It's a stepping motor, the clicks are the valve moving in slight increments. It's normal, leave it alone.

I was listening to my car today and with the clicking sound I can hear through my intake something that sounds like a drum beat and it has a rhythem. What else can be causing this bad idle?

Guys, I have found a way to make the IACV to stock clicking. When the screw is open too much the IACV clicks, so I closed it more and the IACV stopped clicking. HOwever, now my idle is around 550 and when I come to a stop from a roll the rpm drop to around 350-400 and then the computer catches and brings it back to 550. How can I fix it from dipping and to make it idle at 650?

1. warm car to normal operating temp (ie. drive it around awhile).
2. turn car off. Tighten down IACV screw all the way down (closed). Take TPS off.
3. turn car on and rev it a few times then let the car settle at it's set base idle speed. The ECU will not correct for any anomalies at this point. If the car dies, the base idles is WAY too low.
4. adjust the throttle plate set screw so that the idle rpm is just *slightly* under what you want it to be. The set screw is the screw that the throttle plate (in the throttle body) arm rests on which leaves the throttle plate slightly open to give you your idle speed.
5. adjust the IACV set screw until rpms increase to what you want (ie. fine tune idle speed). You can only open it so much (and up the rpm accordingly) so you want the throttle plate screw to be fairly close to proper base idle.
6. turn off the car, reconnect the TPS and fire her up again, cause you are done.
