    I would have thought the first port of call would be the CAT. If that checks out fine, then you might have a dodgy oxygen sensor. Failing that, a dodgy MAP sensor... The list goes on. Get the car to a dealership, so all your sensors can be checked out.

    the cars out of mot though and the nearest citroen dealer is 40 miles away will get a new cat as i had a look under the car today and im not too sure if the cat is okay or not. theres dents on the front of the cat, presumably from speedbumps, and it looks like the inside has gone so il get another one and if that fails then i dunno. cheers guys
