Re: New accelerator pedal
Have you checked the sensor out? DTE shows the pedal sensor consists of two 1kOhm pots, one on pins 1, 2 & 3 and the other on 4, 5 & 6. 1 & 4 are the sense pins with 1kOhm series resistors so check that the resistance on these changes smoothly as you move the pedal.
It might be possible to dismantle the potentiometer and clean the tracks inside to restore it to health for nothing - worked a treat on the moving flap air flow meter on my Mk2 Golf GTI.
