Is this the same thing as EACV - electronic air control valve?

Don't clean it with Carb cleaner. That's the best advice I can give you.

There are things to clean....

The best stuff that I have found is the AMSOIL Power Foam engine clean. I have used this material with phenomenal results. An Integra GSR went from an idle of 600 RPMs to 1400 RPMS with one cleaning and then I could turn the idle screw back in. Awesome stuff. You can use carb cleaner, but it is more aggressive to plastics and the control module.

Pull the intake and TracCont throttle off, pull the throttle body cover off the side (so you can get to the cables), start the car, commence to spraying the Power Foam into the throttlebody while you rev the engine to keep it from dying, aim the stream mainly at the plate and the bypass hole in the throttle body, wipe the interior of the throttle body out, put everything back together.

For an overall intake cleaning, try Seafoam. Follow the directions on the side of the bottle, just don't put any in the oil. Use it all in the gas tank and intake.

Actually it doesn't work off of coolant at all. It's pulse width modulated and controlled by the ECU. The reason why I said don't use carb cleaner is because ^ is right that it is more aggressive to plastics etc. No, you can't use carb cleaner because you'll either ruin your IAC or shorten it's life greatly.

And guess how much a new one is, mmmm bout $300.00, so you take the risk if you want. $300.00 was the price at Autozone and Oreily's who would have to special order it. Dealership has the same price.

Send a message via AIM to Rumnarv
you will notice an idle air control problem when your car won't idle at all. It will run all day long w/ your foot on the gas but as soon as you remove it bam it dies. All that IAC motor does is open a small air passage around the throttle plate to allow the engine to idle. If you want to see what i'm talking about then unplug it and try and get your car to idle. Jumping idle on a honda is usually not an IAC problem. Personally I've never had to replace an IAC on a Honda before, so that being your problem is highly unlikely. Usually only Chrysler and Ford products suffer from this.

Funny everyone I've ever heard say anything about the IAC has always said to NEVER use carb cleaner or anything else that is as caustic. Don't take this advice please, it may work, in fact it probably will but at least use Intake manifold/ throttle body cleaner. And yes they are different don't you dare argue with me. Who told you to do that/ who have you seen do that, some old man huh? Damn, it just pisses me off when people give advice that could be bad for your car.

So you really believe that carb cleaner is ok to use on an IAC or maybe like an EGR solenoid or whatever? Well you go ahead believing that; I could easily prove you wrong, but there's no point you've been tainted by idiocy. Go ahead and use some carb cleaner on someones IAC and it will gunk up even more than it was before if it doesn't eat up the plastic first.
