Default help loss of power fiesta 1.25

As it's a 1.25, first thing I would do is do fuel filter, then check co and suspect a buggered lambda, at least they are easy to change out on these, being at the rear of the engine sticking up out the exhaust, can be seriously tight though.

I have seen MAF meters fail on these very often giving them symptoms.
