Forgive me if this has been answered before, I'm new here..........

After a good few years stuck with jap motors, I've finally had an epiphany and returned to my first love, Ford.

Needing something practical to ferry my two young grandchildren around in meant five doors was essential so this, added to the fact that I'm very skint, has led to the purchase of a 1999 Ford Focus 2.0 Ghia.

The car has a "hesitation" problem, which is best explained by saying it has a big "flat spot" - this happens most when changing gear, but has happened when crusing at a constant speed on the motorway.
I've looked around on the net to try and identify the fault and suspect it may be the coil pack. Anyone care to confirm the possibility ? Should I be looking anywhere else - fuel pump etc ? The car also seems to run very cool - does this indicate anything ?

I'd appreciate any advice - from reading other posts on here it does seem that there is a lot of knowledgeable people on this site.

Thanks in advance.
