OldMechanic,
If you have questions specific to the car drop in to
Fiesta Faction: The Ford Fiesta Enthusiast Community Forum It is a good forum with plenty of good info on the car.
Also don't drive the car like a regular automatic. It is an electronically shifted manual and learns how you drive for about 2,000 miles. If it is shifting at high revs then it has already learned to shift that way. You may need to visit a stealership to get it put back into learning mode.
Enjoy it.
Edit: make a fuel log and join team Ford.
