Sticky juice: C250TD

[Oom]

Sometime when I floor my C250TD, the car keeps accellerating when I take my foot off, until I touch the brake! This happens sometimes even without clicking the kick-down switch under the pedal. I know the cable is connected to and electronic unit which then drives the pump, and the cable seems to be ok. Any similar experiences?

Are you sure you are not activating the cruise control by accident?

Otherwise make sure your overmat is getting stuck in the accelerator pedal.

There is a return spring inside the fuel pump, it could be broken.

It miight be worth checking the throttle potentiometer too to make sure that it is rleasing properly.

Will do, thats a great help. You guys certainly know more than our local MB dealership.

Nothing like that. I am very suspicious of the potentiometer. Would a broken spring in the pump not mean that it would do it at random, not just when the pedal is near max?
