Ok I don't think it will be the cat, as the lambda sensor is before the cat.

If the lambda has not been replaced then it's likely to have gone faulty. Don't buy a 'universal' type as they're nothing but trouble from what other owners have said.

Before you start changing the lamba, you need to look at other sensors that the lambar reads off. the throttle pot sensor and air sensor at the single injecter unit might be faulty or dirty. With overfueling, its possible the lamba and cat are now damaged. You need to find a garage who can read the codes. A good bosch agent or fiat independent should be able to sort you out. Money well spent.

got there today tried all the fiat data things on it but none worked ( couldnt read control unit) so none the wiser although the garage did suggest I check the time-ing and if that dont work use thee old multi meter test on everything takes a lot longer ladies an gents but somethings gotta show up (I hope) other than that they couldnt tell me anything else ...........so can anyone tell me what does a fiat tipo 1.4 ie normaly do to a gallon??? a know theyre better on a long run cause there isnt much stoppin n startin an stuff but am sure round town an that they must do more than 23/4 to the gallon anyway if a find anythin out bout mine al post it on here so for now many thanks Hellcat and sumplug al be back soon......pete
