I've got a problem with a lack of power, I've run three lots of injector
cleaner through it and local Fiat specialist put car on test and said that
Fuel Pressure Sensor was duff. This was replaced and the car was 'slightly'
better but still not perfect. Turbo's working Ok as problem only seems to
occur in third to fifth at 2-5k revs. Air flow sensor ? no smoke visible and
low revs from stand still accelerates fine. Any ideas anyone ??
