Default ***How-To Clean*** Your IACV a.k.a. Idle Air Control Valve

The function of the IACV a.k.a. Idle Air Control Valve is to adjust the idle based upon the amount of air entering the engine, then the computer reacts to this information by adjusting the cars rpm.

Reasons why you should take it apart and clean it:
-High idle after your car warms up
-Lumpy idle
-Roaming idle
-Hunting idle
-Fluctuating idle

Tools Needed:
Ratchet
12mm Socket
Pliers
Brake Cleaner or Simple Green
Paper Towels
A cooled down engine for at least 2 hours

1) Now you got to locate where the IACV is, pop your hood and itís located directly behind the intake manifold. Itís actually connected to it. Remove your intake and strut tower bar. (If applicable)

Click the image to open in full size.

2) Place a couple of rags underneath to catch the coolant spill. Loosen the two hoses running to the IACV with your pliers by squeezing the two clips and moving them away from the end, circled in yellow. DO NOT cut the hoses as they are the exact length and you will have to buy new ones if you do.

3) After doing that remove the harness connected to the IACV on the driver side, circle in blue.

4) Then to finally remove it from the intake manifold, remove the two 12mm bolts, circled in red.

Click the image to open in full size.

Now that the IACV is removed from the intake manifold make sure that you do not lose the rubber gasket as you need this so that it does not leak after you re-install the IACV.

5) Take your brake cleaner or simple green and start to clean up the inside of the IACV by spray inside the two holes. Continue to do this until no more dirty fluid comes out. Should take anywhere from 5 minutes to 15 minutes. This depending on how old and dirty your IACV is. The gasket can be seen in this picture as well.

Click the image to open in full size.

6) Once youíre done cleaning out the IACV let it air dry. I let it air out for 20 minutes while I did other maintenance on the car.

Now your ready to re-install it back on the car so follow the steps backwards from 5 Ė 2



Good Luck

hmm I've never done this, 226K miles on car, and I sometimes have a very slight fluctuation up and down from about 650 to 750 rpm. This could fix that?

Would it by any chance fluctuate when the A/C comes on?

Hey thanks a bunch man. I actually did this today for the first time (on a 103k car) and couldnt believe how dirty it actually was, and as far as I can tell, the rpm fluctuation stopped. Good write up too, all instructions were clear
