accelerator pedal

Hi any ideas new to forum Iv'e got a 04 TF and have changed the throttle cable as it was very notchy and it made a vast improvement but my pedal is still very stiff and heavy, causing loads of problems in traffic could it be a problem with the pedal itself?? my bundle of joy is definitely going down on my fun factor chart

Disconnect the cable at the pedal and see if the pedal is rotating correctly on its pivot. Some lubrication might be necessary. Helps if you're good at potholing.

I found that easing the fixings and bends along the route helped smooth the action greatly.

Thanks for your prompt reply I have taken the pedal off and looked at the nylon bungs they are very grooved so do you think that this might be the problem as it might be sticking as you press the pedal down. I have checked the cable run and no kinks in cable also checked the function of the throttle body and is fine. Ron

Just had a new soft top fitted today went for the black with glass window transformed the look of the car . The bloke that fitted it took about 3 hours and only charged me £500. Shame I can't get the nuisance to drive smoothly. Might have to resort to taking it in to MJ Autos in Littlehampton..

Hi Ron,

I have exactly the same problem with my 04 TF. I've bought a throttle cable to replace (haven't yet attempted the job) but apparently you can buy replacement nylon bushings from Rimmer Bros.

I had a similar problem and probably like most lubricated the cable using WD40, you should not use oil as I understand that the cable has a PTFE liner. This improved matters for a few months after which it started to stick and snatch again. I used WD40 again but when picking up some oil I noticed a PTFE based lubricant which I used next time the cable started to drag, this improved the situation and was longer lasting.
However, when I had the rear shelf cover and the sound proof wadding out of the car I had reason to drive it and found the accelerator cable problem had effectively disappeared. I noticed that the cable route formed a raised curved profile which caused the cable to pinched or flattened once the sound proofing was refitted. I cut a slot in the wadding under the rubber sheet to accommodate the curved profile of the cable and the situation is much improved.
