Unplug the TPS, clean out the throttle body and put back together,

If it clears the fault for a while its the TPS,

Just changed mine as I had the idle problem, which builds to it dropping out of over drive when cruising and also not liking cruise control.

Jedi had the same problem, I removed his TPS and reset fault codes and it is working perfect at the moment but i have a new TPS on route to him.

Its a cheap simple fix if you put a new on in.

If it isnt that at least you haven't spent a fortune. Email Carols Fandangos, he has a few spare TPS's for cheap money that and tested and working.
