Here is a youtube video showing diagnosing what should be the same IAC as your car. I had an LH 2.2 IAC that showed within specs yet still caused a higher than normal idle (1200-1500rpm). I didn't watch the entire video, but thought it interesting he mentioned getting the diagnosis instructions from Autozone (go ahead and finish your TPS diagnosis first as you started there).
