   and how badly did it fail? Borderline cars I have found can be got through with some decent fuel, redex and things like cleaning the airfilter / induction / breather system and a good thrash. Give them the car warmed up as catalytic converters need a bit of temperature to work effectively.

   Stop throwing your money into mot's without solving the problem.. Get then to quote you how much to fix it... Or at least tell you how to fix eg parts needed..
   
   Fix it.. Retest.. Pass..
   
   Simple.

    The cat was just on the car when i got it. Everything is sorted now i think, just need to get it retested. ona get a second hand air flow meter that might be the problem. il let you know how i get on with it.
