A mate of mine had the same problem, failed its mot on emissions, the garage ran a diagnostic and it came up with faulty lamba sensor. Replaced the sensor but the problem was still there, the garage said because the car was being driven with a faulty sensor, too much petrol had entered his catalytic convertor and this was as fault as well, had that changed plus a service and change of plugs and the car passed its mot at a cost of

cat is working fine because the co output is zero indicating the cat is doing its job ok,i cleaned the old probe today and ran a can of forte fuel system cleaner through the inlet vacum pipes and some in the egr system to clear it out the rest in the tank ran for a bit till normal temprature and tried again and co is zero and the lambda was 1.00 perfect so im going to run it for a few days n try testing it again just to see if it settles ,a mechanic i know says it could be the air flow meter giving truble and he sugested running it with the wiring disconnected and if it goes better relace it,so i tried and it does go much better so i may get the new meter asap :angry:
