sticky acc. pedal.

(1/3) > >>

vettewest:
My C4 has a problem with a sticky acc.It's not the pedal,I've pulled that to pieces and greased it.It's not the cable, I've oiled that.I'ts not the throttle body,I've had that bushed with teflon sleeves.The throttle is easy to open and does not bind when the motor is not running.However when the motor is running the throttle is very hard to open.Seems to be a vacuum problem to me.It has been suggested to me to drill a small hole in each of the butterflies to cut back on the vacuum.Has anybody got the same problem and has anybody found a way to fix this......gw.

Is the pedal just as heavy with the engine off as it is with the engine running.
If it is the same it is not a vacuum problem
It is either the the throw of the accelerator pedal, the angle of the accelerator cable to the pedal or the cable. After you lubricated the cable was it easy to pull the cable when it was out of the vehicle?;38

I've moved it here.  You should get someone chiming in soon.

OOPPS. Chromie was replying when I moved this.  Have you found it again Chromie?

Was is it sticking before it was rebushed?  Supply as much as info as possible.  Why were the bushes replaced?

I would think twice about drilling any holes.
