Had the same problem myself - throttle position sensor showed faulty. Although the TPS is a sealed unit, I managed to get it apart and found moisture on the potentiometer. Clean it up, dried it of, glued it back together and away we went - for a week. On retesting the idle setup, the TPS was found to slightly mis-adjusted - reading around 0.6v then dropping slightly as the throttle was opened, then rising. Set it up with idle at the lowest possible voltage and risng voltage only as throttle is opened.
