Duke, thank you very much for the input. Can you explain a little bit more regarding the TPS? I don't quite understand exactly how it works. Are you saying it is an on/off type of component and should test as a closed circuit at idle? What should it read at WOT? Also, between which 2 leads should I be testing for continuity at idle? Would it be possible (or even safe) to unplug the pigtail while the car is idling high and jumper the 2 leads to see if that brings the idle down?

I will run out perhaps tonight and check that - I hope it's the culprit. But why did my idle improve so greatly when unplugging the ICV?

Oh, and any thoughts regarding my previous question of any damage caused to trans or torque converter as a result of elevated idle?

Again, thanks for your help everyone.
