After installing new bushings in the pedal cluster the engine idles too high. Reason is that the throttle body return spring seems a bit too weak to fully close the intake on my 1971/4. (The pedal moves freely, but now with a bit more friction due to less play and some grease.)
A Little push with the finger and idle is okay. Is there any possibility to add a second spring like on the later cars? Or should I just install a heavier spring to solve this issue? Any comments on this will be appreciated.
Greetings, Arno
you only changed one thing mate.
sounds like its sticking before it can pull right back/
i don't know if you can lube the bushings a bit.
years ago when i converted mine to rhd i had a similar problem briefly.
but it soon settled down.
maybe take it out on the autobahn and give it a bit of florian schneider and see if it comes good with a bit of pedal action.
Are you 100% sure you didn't twist the throttle cable around the clutch cable inside the center tunnel?
I would check that first.
Also check the rubber gas pedal. It acts as a spring too. If it is mushy at the bottom it has lisy the spring effect. If the cables are crossed depressing the clutch will accelerat3 the engine. Pull the cover plate at the front of the tunnel and look in with a mirror and light.
I had a similar issue; turned out the moving parts at the throttle body needed a shot of lubricant. Still apply about every 6 months...
Hello all,
thank you for your replies. I checked the cable, no collision with the clutch cable. The mounts inside the tunnel are good (picture). I suppose it is the pedal, together with the cable beeing a bit too tight after fitment of the new bushings (the gas pedal bushings where all gone). I will reajust the cable end at the throttle body to give it some free play and recheck.
Arno
If you give the cable some free play, make sure the pedal stop on the board is correct or you will never be able to get wide open throttle.
