    Fiesta 1994
  1. 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?
  2. 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
