Since cleaning my IAC, the engine is running higher rpms at idle (1900). It also kicks up a bit while I'm driving and take my foot off the gas to slow down (as the revs drop and I slow around 1200 to 1300, the computer kicks in and takes it up to 1800 or so)

I've left it running for 15 mins in park, and the "computer" has not readjusted. Is this supposed to happen naturally (been driving for 3 days and no change).

What can I do here?
