I've got an N reg 1.25 Fiesta Zetec with 80k on the clock. It starts
first time every time and runs fine and smoothly. However I have the
following two problems.

Problem 1.
After starting, although the engine sounds fine its absolutely gutless
and has a real job pulling away up a slight gradient (yes I AM in first
gear and the brake is off). Once its warm its OK. No problems at all.


Could this be a misfire? We had this problem and apparantly it's quite
common.

Problem 2.
This started after the service and it didn't happen before the service.

Did you happen to have new spark plugs fitted at this service? If so then
I suspect you have a bad misfire (probably plug lead one from what I
remember). I think this problem got so bad on the mondeos that there was
actually a technical bulletin sent around about it - I *think* the fiesta
Zetec suffers the same way.

Yes we did have new sparks. Apparently the HT leads are carbon fibre
rather than metal although I can't remember the reason, something to do
with durability, but they tend to snap!

It runs really smoothly so I don't think its a misfire. It really
doesn't feel or sound any different below 4000rpm.
