Temp is always below 200f. Doesnt matter what kind of driving I do, whether its to the gas station right up the road, or Orlando 2 hours away...it does it at complete random. It basically starts as soon as I let go of the gas, the idle stays a little high and sticks for as long as it feels like it. There is nothing I can do to make it go away. If I get back on the gas, it sputters and stalls for a few seconds unless I floor it, then it sounds like its mis-firing all over the place. I havent tried cleaning out the IAC passage though, good idea, Ill let you know.
