My 1994 Fiesta failed on emmisions (CO 1.26 HC 2.44).
The garage said the next thing to try was a new cat & lambda sensor.
Would this definitely fix the problem or is there anything else that could be causing the problem.
Also is it fairly straightforward to fit a new cat & sensor or are any special tools needed?
Many thanks

Many thanks.
But does that mean that it could be just the sensor, or it could be just the cat.
And I wouldn't know which until each was replaced and re-tested?

i would go for the sensor first as its a lot cheaper than the cat

Chances are it's the sensor as they only last a certain number of years.
