my s2 is running rich. hydro carbons are up at 4000 and the mot limit is less than 200!!

its idling a bit high and when i take the revs down a bit it starts to hunt.

any ideas?

You have an air leak that some one has tried to mask by turning the co screw. Mine was a pipe on the back of the inlet manifold.

sprayed the inlet side with brake cleaner, no change in the engine speed or sound.

put the car on a gas anilyser and set the co and idle speed, sweet i thought. next time i go to the car it wont idle. turn it up and it runs fine, next time you go to it i revs up?

strange eh?

cold start sensor?

you need to get it setup and have it tuned fella. If you dont know or understand how the system works you need to read a setup guide to help you.
