Hey bazz, ive just had probs with my fiesta and revving probs and i got told it was the idle vavle. I removed it today, cleaned it with carb cleaner and it works a treat...you mite wna try it. Other to that check the sensors are all on correctly...mainly your mass air flow sensor.

goodluck
Nat

was it just a code reader your friend used? a live data diagnostic tool would let you see what the TPS is reading when you press the pedal.

is the wiring to the sensor ok?

Don't know what sort of reader it was,will ask when i see him,Going out now to have a quick look at the wiring to sensor.

Ive noticed that the TPS makes a buzzing sound when i turn the key to ignition, then goes off when i turn the throttle then goes back on when i release the throttle, is this normal
