Hey friends. I've tried searching but came up with nothing. I've got an '03. I had some intermittent jerkiness in my throttle, no code, so I decided to put a new TPS on it to see if that fixed it. After setting the idle by the tach, it now will not downshift at wide open throttle. I can downshift it manually though. I've tried adjusting the revs a little, but nothing has worked. I put the old tps back on it and got the same results. Am I missing a step? Any thoughts?
