Accelerator sticking

[Guest]

Hi can anyone help? [8|]
I noticed whilst out and about this weekend that when taking my foot of the accelerator to change gear, or even when stationary, the revs stay high, this is being caused by the accelerator pedal not retuning to the original position (I must have my foot to the floor to often).
As the other half is spending every waking moment resoring his mini, I will have to look at it myself. []
Will it just be a case of a bit of good old WD40 or is it a bit more complicated.
Any suggestions would be greatly appreciated.

Hi - I found much the same when I first got my 911, and discovered that it was a simple matter of removing all the carpet, removing the pedal body from the linkage and trying to see which part was sticking.

In my case, it was simply the carpet just catching onto the plastic pedal body, and I all I needed to do was to re-fit the carpet in the correct way (some previous owner had layed it rather haphazardly).

All is now well.

If this doesn' t cure, then although the linkage is still suspect, then you might be looking @ an air leak.

However, to eliminate the linkage, then look inside the engine compartment when someone is operating the throttle. You will see a linkage moving@ the top of the engine bay.

When the passenger is in the car (ready to turn of the ignition in case of trouble) then grab hold of this link in the engine bay and just tweek slightly / rapidly. If the revs of the car follow the movement you are making, then you know it' s linkage related.

If they don' t then the cause is elsewhere

Thanks for your speedy response. Seems easy enough, I' ll have a look over the weekend and let you know if I cure it.

I had the same problem.

The accelerator rod goes to a lever attached to the gearbox.

This is exposed to the elements (visible from under the car) and mine was gunged up with grease, dirt and " stuff" .

A couple of circlip type things hold it in place and the car has to be jacked high to be able to get to it. When I removed it, it was also a little rusted. I took it off sandpapered the rod the lever slips on to, and the inside of the lever shaft. Regrease and all' s OK now.

I' m sure someone will have a better description than the above but at least it may help.

Regards

Hi
I had the same problem on my 89 3.2

Found that a small stone had lodged behind the linkage under wooden floor board.[:-]

It was only matter of taking up the carpets disconnecting accelerator pedal from its ball joint (just pull),[] remove the two screws that hold the board down then you can see all the linkages so you can then clean all the muck etc out

Its then just a matter of going in reverse hardest problem is getting pedal back on the ball joint use[8D] a pair of mole grips to hold the rod when pushing pedal back on.

Had the same problem with my wifes 964 but it was the clutch pedal that time.

Hope this helps[]

Finally got round to sorting mine this week (after paying Sp*******t C**s to do it at the last service and they didn' t seem to bother)

Went through the linkage from front to back and mine was the same problem as Lloyd had - the linkage on the gearbox was very stiff. Removed it (or partially removed it - the banana arm prevents it coming right off and taking the shaft out lets the oil out of the box) - good clean, derust and pump full of grease and everythings fine.

I need to check the compatibility of grease with the nylon bushes to see if this is a long term fix (I may replace with Oilite bearings if not)

Maybe this would help you, im looking at it for myself as my 964 has split nylon bushes on the throttle rod running across the footwell connected to the throttle pedal, Assuming yours are the same as a 964 ??

Those bushings are for the pedal box - the ones I was looking at are for the pivot point on the gearbox. I' ll see what I come up with (and whether it' s actually necessary - there' s not much stress on the nylon ones after all!) and post my results

I have to go along withn the gearbox mounted lingage,,just jack the car up & spray loads of WD40 whilst moving the linkage,this should cure the problem.I had this on my ' 89 3.2 Clubsport,it certainly made things interesting for a while!

Just thought I' d post an unexpected bonus after doing the gearbox linkage. For a while I haven' t been getting full throttle (check it - you may be surprised) and have played with linkage adjustment to get that sorted with limited success. After cleaning and greasing as outlined above I decided to have another go - no need the work had found the extra half inch or so I needed!

Now for some decent weather!
