IACV-- what's the best way to clean this sucka?

I'm going to clean out my throttle body this weekend, and was wondering what is the best way to clean out my idle air control valve (IACV).

Should I use the same stuff that I use for the TB (combustion chamber cleaner), or should I try a little DEEP CREEP?

Also, for those of you who have K&N filters: are there any alternatives to washing, drying, and then oiling them?

That's what I have been doing in the past and to make sure that I get off the excess oil, I run a leaf blower through it set on low.

Don't run a leaf blower through it. That can damage it. Do what the directions say on the box for the recharge kit. I believe it says to run it under low pressure lukewarm tapwater after you spray it with the cleaner and let it sit for a little while. To answer your question, no, there's no alternative other than getting another kind of intake or a paper filter.

Disconnect the 3 wiring harnesses, mark them, and disconnect the iacv from the upper intake man. Then open up the iacv, spray carb cleaner all over it. Wipe it down clean, and put everything back together. Done!

The harness/connectors are color coded - not sure what the point of marking them is...

To me, there's no point, but when people in the org does a simple pulling of codes from their ECU and manages to fk it up badly, I figured that thinking with the certain type of mindset some people have, is a good thing to incorporate when giving a detailed instruction.

if you want, you can take off that gold shield thing, and clean inside. make sure you use the write screwdriver so you dont strip those screws.

If you don't have an older stock air filter lying around, you may want to go get one. It's good for temporary use while your K&N is drying/being reoiled. I have a stock filter that I've used only when the K&N filter was being 'recharged'. After cleaning it, I just leave it to air dry completely, then apply only enough oil to get it pink. After applying a small amount of oil, I usually let it sit for a number of hours while the oil permeates the material. The I touch up the bare spots. This is to make sure that only the bare minimum amount of oil is applied. If you overoil it, that excess oil is going to end up coating your maf sensor, as well as end up on your throttle plate and beyond.

Just cleaned my IACV tonight. Took it almost completely apart, doused it with carb cleaner, and used a rag to wipe it. For some of the hard-to-reach spots, I used a soft toothbrush. For the others, I just held it out in front of me and sprayed carb cleaner at them until the gunk washed and dripped away by itself.

I couldn't believe how much crap was in there. My bro and I joked that 15hp was sitting in a puddle on my driveway by the time we were done. But that was nothing compared to what I could see of the inside of the intake plenum. That really made me wish I had a lot more time for cleaning...
