I have an L plate 1.1 fiesta, it's burns a bit of oil and smokes a tiny bit, the engine is tired, but other than that tip top.
It failed the MOT on emmissions, all else fine
CO 1.56% rather than 0.3% HC 298 rather than 200 Lambda OK
I was wondering what the chances of a new CAT fixing it are? And whether it's worth gambling £80 for a CAT for a £250 car
I'll fix myself ...
or could I go for a second hand one? or could it be the lambda sensor? or can I clean the old one? or should I just scrap car?
(I can't adjust mixture, it seems to be all auto in this model)
Any comments appreciated
Cheers
