hello my name is david i own a mk2 fiesta 1.1 it as done about
98 thousand miles the problem is it only does 30 mpg i have had it crypton tuned but it still seems the same could anyone tell me how good they'er fiesta is on fuel on town and long distance journeys

david, February 2008

Assuming that the car is a five speed gearbox, I would expect it to average at least 40 mpg, more on a long distance run.
Personally I would check the entire ignition system first and making sure that everything is within the tolerances and in good condition, ie ignition timing, valves, spark plugs.
Has the air filter been renewed recently? If it hasn't, it won't help matters as a filthy air filter can cause the engine to run rich.
Once the ignition system is checked etc, take another look at the carburettor.
It is possible that the carb is badly worn which may also account for the engine running rich.

Hope this helps
