Top of block/head, one end either 2 or 3 wires. X 2 with Mr.I, if they can't find a standard part on a common vehicle what does it say to their expertise? Could also be the engine management. 2 tips, a)try disconnecting the battery terminals and hold the leads together for about 10 seconds to dissipate any static that worked once on an LS Lexus with the same symptom, b) They should have had a decent diagnostic unit 2 minutes to tell you what's wrong. Incidentally these sensors are solid state Hall effect switches they almost never go wrong. Also look at the fuel pump and air valve.

I just noticed you're UK based where?
