N.Y.
I understand the thinking, I just haven't seen it, except one time when the screws were a little bit loose, so it was able to vibrate with the engine idling, just enough to cause the TPS to go from a good spot to a bad one. I'm not saying it can't be the TPS, I just like to learn when I can! Keep in mind that I am presuming that no one is touching the throttle at all. When someone feathers the throttle, and it jumps like that, then it is often the TPS, in my experience. Appreciate the input.
Take care,
