Hi guys,

looking forward to participating in what looks to be a very busy community. however straight to the point...

My 2010 model Ford Fiesta Zetec failed its first ever MOT (obvcourse 3 year old car dont require MOT's) and to make things worst ive only had it 5 Months

My MOT emmisions results from 2 garages are as below :


max for CO should be 0.20%
max for HC should be 200ppm

GARAGE 2 (After bottle of Catcleaner)

Fast Idle Test
CO 0.30%
HC 348 ppm

Second fast idle test
CO 0.67%
HC 314 ppm

GARAGE 1

Fast Idle Test
CO 0.52%
HC 393ppm
Second fast idle test
CO 0.93%
HC 216ppm

Anybody advise on the steps to take to try resolve this isue?

I was told it could be the oxygen sensor (if anybody knows a rough price for one?)

regards

craig
