Haven't done either a voltage or resistance check on the TPS. Tried to get access to it today to see if we could try moving it and oh, it's going to be such a pain in the mk1 engine bay - we've got water pipes running under the inlet manifold which wouldn't be there in the Sierra or Escort Cosworth. Fun!

I think that's going to be next on the to-check list if I can persuade my wife to let me have another day working on the car tomorrow, instead of sitting in traffic waiting to go somewhere along with everyone else on bank holiday monday....
