Cheers for the info people. Am gonna crack on with this stuff now the weather seems to be clearing. Didn't want to risk doin anything and getting it wrong cop my hands were cold lol. Cost me an arm and a leg over xmas and stuff tho. The only sensor i read in this thread is the camshaft position sensor which is on the top of the engine about 6 to 8 inches to the right of the oil filler cap.
