Sticking accelerator pedal

[les]

Well I think lack of use has finally got to my S1 over the winter. My accelerator pedal seems to be sticking. Initially thought it was either the TB sticking (its still the plastic 48mm TB) but it looks ok, and is free to manually turn. the exposed cable itself looks clean and clear and everything points to the pedal mechanism. I noticed over on pistonheads there was a similar discussion http://www.pistonheads.com/gassing/topic.asp?t=964004. Has anyone else experience this? Cars booked in next week over at SLS but for obvious reasons would rather sort this first.

Unfortunately a fairly common occurrence with early S1's.

If you have discounted that the T/B end is not sticking, then it is probably occurring at the pedal box end. Initial attempt is to spray inside the outer cover with a good lubricant, ie silicone, but not WD40.

I believe Mr Sheen (or similar) is good for these types of task. Sprayable, leaves a slick-ish coating behind. Also good for the internals of window winders.

And GT85 bike lube, leaves a graphite residue I believe.

An uprated throttle linkage may be of use, see Eliseparts.

Make sure the 2nd spring is still attached, it's attached to bonnet release cable.

Thanks guys, I'll check the second spring (just in case) as i only remember seeing one spring and try and lube up the mechanism. Wonder if its worth installing the upgraded linkage.

I just installed the upgrade linkage and it's very good, giving a much smoother pedal action. It's very easy to disconnect the accelerator pedal from the linkage, so maybe worth doing that to isolate the pedal and see if it's the pedal itself or the mechanism thats sticking.

Replacing the linkage took all of half an hour and most of that was procrastination.

use Campbells GT85 lube suggestion (£2.49 in halfrauds) and it seems to have resolved the issue. Drove through to SLS with no re-occurrance so fingers crossed its been lack of use and old age. Thanks for all the suggestions

Crikey..."Campbell in tech help shocker" :shock

Glad that's helped. May not be a perm fix but seems to have taken the sting out.

McKean kindly helped lash an Eliseparts kit into my S1 (my original collapsed), after having done several to his own over the years, and I've never looked back since. He also found a damper issue at the same time, on "shakedown", but that's another story

Ali had a look at this for me also when the car was in the other day, TB is also starting to stick, anyone got an alloy version lying about?? see wanted ad in Classifieds

I have a 55mm throttle body it requires modification to fit but it's free

Nizzy, thanks for the offer, I've seen the conversion done on Dieter's car when I had the mgf, I'm assuming the the VX TB that you have. This time I'm going to take the easy option and go for Robin's option of the 48mm alloy TB.

Thats the one, I will put my pens back in it then
