Hi all,
What could be the symtoms of a fault tps please?

In summary, the throttle almost seems to have a 'mind of its own' eg erratic and sometimes surging idle, hesitation in acceleration / pick-up, out of the blue stalling / cutting out both under load and idling.

Thanks for your reply, that sounds right then, as my car was undrivable last weekend, mostly running much leaner than intended. I am also going to check fuel pressure and if I have some sort of ristriction in the fuel system.

Also check it hasn't just come loose and moved.

No it's tight. What made me think it is faultly, was the fact that on idle it is supposed to read 0 MBE ECU according to the tuner, but occasionally even went up to 4 with no throttle, however it is intermittent, as yesterday I exercised the throttle several times, but it always went back to 0
