Throttle Pedal reset: Erratic or fast tickover:
Could be because the throttle butterfly is stuck - or is not matched to the accelerator pedal potentiometer:
- Switch ignition switch off then on for 15 sec or until a "wheezing" type noise stops.
- Switch off for 15 sec
- Depress accelerator fully; switch on ignition for 15 sec then off again. Do NOT start the engine.
The pedal and the throttle should now be matched.
