When I arrived on site, I placed the ECU vacuum hose from the throttle body, directly to the intake manifold. I then returned to the shop and ordered the pot sensor assembly.

Returning on site days later w/ the part; I asked if the problem returned. The operator(s), (who happen to be as intelligent as very young camels) replied " no".

I still replaced the pot, and check the voltage sweep. It was basically the same as the original. I did notice, that on start up, the engine slightly rev higher momentarily then dropped to normal.

The problem has not reoccared, so the answer is a coin toss. Too many variables to know for certian.
