How do you reset the idle air control, once you replace it, or does it do it on it's on...

you just bolt on the new one with a new gasket and plug in the electrical connector. i don't think you can "reset" it. idk, i could be proven wrong cuz i've never actually replaced mine, just cleaned it...

you may want to disconnect the negative battery cable for a while and then reconnect it in order to reset the computer.
that way the engine will re-learn the proper idle speed.

what is the best way to clean the valve

 

[Wicked_Sludge]

no need to unplug the battery, the PCM will figure it out on its own.

to clean the IAC, i usually use a small brush (a toothbrush could work) and brake cleaner (the kind that causes cancer, not the wussy chlorine free stuff). i also grab the shaft inside the valve with a pair of needle nose and unseat it so the brake clean can clean the sealing surface of the valve.
