I replaced my TPS on Saturday and that fixed a bunch of bugs. Idle is smooth all the time, no more hesitation when cold, and no more lean bank one/two CE lights! It was reading 730 or so ohms to 3.2K on the car so I replaced it. When I tested it on the bench it read normal - I hate intermittant problems. This is why the scanner didn't catch it during the KOER test, it was working at that moment. Funny, the new one read 400 to 3k ohms, the book says 300 to 6K. The car runs way better, that's what counts.
