Weird Idle Issue after WOT?
Once it was the Cruise Control binding up, took me a couple hours to figure that one out. Then the last time, my buddy unclipped the throttle cable and it wouldnt shut the TB all the way, but that wasnt after WOT. Try pulling your IAC motor out and cleaning it off, as I am thinking about it, that was a cause a couple times, but not as bad as you describe. Two torks bits, wipe it off with soft lint free cloth, clean inside the bore as well.
