Can anyone help me, my car only just passed the MOT the c/o emissions were high, was told to change the o2 sensors which I have tried, made no difference, can the c/o be adjusted ? it is all getting a bit complicated and expensive. any ideas would be very much appreciated, thanks.

Sorry got called out to work, the only other reading on the MOT printout is HC this was 358ppm, the limit is 1200ppm. the cats are still in place. car runs O.K. does seem to use a bit more fuel then when I first got it, only other thing is after a run the idle hunts for a bit before returning to about 850 RPM it's an auto, but having read lots about this car the idleling is a bit of a problem. Don't want to keep throwing money at the problem in the hope of maybe getting lucky, was thinking of trying to get the car into Zed world to see what they can come up with. :confused:

Did you leave it plugged or put it back on after the test ? would rather try to sort the problem then just do a quick fix.

Na mate plug it back in after the test car runs fine "No Broken Don't Fix It"
