Hi ! I have a 1995 Ford Fiesta Si 1.6 16v that is totally standard and has coverd 72,000 miles from new. I have only just begun having problems. The car seems to have a flat spot around the 4000 r.p.m mark ! Normally these engine pick up around this mark but this one has problems ! I have plug the car in to a Snao On heritage diagnostic machine and this shows no faults ! I can only assume that there is either a problem with a vacuum pipe or fuelling ! Have you any idea what it could be ? Many thanks.
hi i think this should go to your local dealer, they can check for faults
