Fix was done by me. IAC valve is located on the backside (toward the driver compartment ) held on by two bolts, upper and lower. Forget about any typically sized torque wrench, there just isn't room. You will need a mm box wrench. Snug the bolts, very careful not to overtighten.

First you want to disconnect the electric connector running from the base of the IAC (believe this is what causes reset) and I myself always remove the battery terminal as a formality to prevent electrical harm.

Anyway, remove the bolts, tilt back the unit and you will see a screen on the left portion sunk in tightly by an o-ring type seal, or so it appears. I made the decision not to remove this screen and leave it in place so the seal could not be altered or damaged. Remove what you can safely scrape down away. Next, I sprayed the screen which was about 50 or 60% clogged by an accumulation of matter with carb cleaner, trying not to "blow" the debris inside the unit, if this is possible, then tilting it in place toward the front end, upside-down to drain and dry. Bolt it back and make the connections.

About the idle reset, my mechanic recommended driving the car for the computer to "relearn" what it must. But what I thought was an incorrect idle was the idle set screw, being so far off to accomodate the clogged screen -- I would plan on resetting the idle screw. Its the only one there.

Also, when you are there, you may want to check the vacuum hoses. moving them around may open existing wear spots. Too the coolant bypass hoses on the frontside of the intake. These are more difficult but worth it to replace all at same time. I drive easier knowing they're done(warning; these can be tough to identify: one local Acura dealer gave me the wrong hose, while Napa ordered one of two right.

While inexpensive, these are molded shape hoses, reinforced. Get the schematic and look for yourself. You don't want to get it mostly apart and find out you have the wrong one. [for this you will need long needle-nose with 90 degree bend and a mini straight needle nose, for the constricted space)

If this doesn't help, post back.
