Are you sure its det?!
if the ECU thinks that sensor is broken, it will back the ignition advacne off a further 3 degrees for safety.

It does? I guess this affects performance. Hmm, been feeling a bit slow lately...
Its running fine, no noticable loss of power but on idle its lumpy at times and it seems to knock randomly. I thought it might be a missfire at first but it isnt. I dont know how normal it is though and my last clio also had a fairly rough idle.
Hows your Idle?

It does, although i should rephrase. If its unplugged it will back off 3 degrees, whether a broken sensor would be detected as "discconected" i could not tell you.
