We are getting an intermittent problem with my Focus 2.0d Ghia. The car completely looses throttle response for between 15 seconds and a minute (always when trying to pull away from low revs). It just sits there idling with no warning lights on the dash (no matter what you do to the accelerator). It happened in the middle of the intersection been suggested a faulty throttle position sensor, but i think maybe accelerator pedal potentiometer or a damage fuel filter any help would be great Thanks
