I followed the directions from a thread here on Rennlist and took my gas pedal assembly off and greased it. I could tell from pulling on the cable (when unhooking it) that my problem lies in the cable itself. It needs lubricating just like the cable on a bicycle brake would. Only problem is that I don't know how to go about it.
Anyone got any ideas?
Thanks!

I'd like to know too because my pedal (or cable) is very sticky. What thread did you follow to remove & grease the assembly?

Van

I think I had a thread about that a while back...

Here it is: https://rennlist.com/forums/996-forum/380904-edit-exactly-how-should-the-gas-pedal-be-removed-feel.html

For what it's worth, I think the actual cable that goes from the pedal is dry - i.e. no lubrication (because lubrication tends to attract dirt).

Let us know what you find.

Yeah, I used Van's thread to take mine apart. I slightly stripped out one of the screws when putting back together, so be careful. Those screws are CHEAP CRAP, much like you would find in a cheap, cheap product. So, be very careful with those screws.
The cable is in a clear sleeve which is then inside the usual black sleeve. Mine feels dry and very sticky when I pull on it by hand.
I've emailed Loren for his help. Will let you know.
A sticky pedal drives me crazy. I would just assume not drive the car (any car for the matter) with this problem.

This diagram shows both the non-egas and egas version of the gas pedal.

The non-egas (MY99 C2 only) uses a traditional cable from the front of the car to the back (shown as the cable coming out the bottom).
Egas cars use a short cable to the potentiometer (item 10).

Loren - on the egas cars can the cable be greased to resolve this sticky gas pedal feeling?
Thanks much guys

BTW - superb DIY write up on the pedal assembly Van....still probably over my head, but superb write up none the less..

Loren

I doubt it - as I recall it is enclosed.
If the pedal is really bad then I think you should replace it.

Why could a simple cable not be lubricated?
If it is inside a sleeve, the dirt should not be a problem.
Even a pot (potentiometer) -egas- can be lubricated.

as for the accelerator feeling "notchy", I recall a study done by BMW a while back,
that involved collecting data of road vibration of the foot on the accelerator, causing more
fuel consumption.
I wonder if Porsche makes the accelerator notchy because of the same reason.

If the cable is "greased" it will become very sticky in cold weather and may fail to move at all.

JDSStudios

Try the right "grease", not glue.

Use the proper lubrication and lower temperature will not be the issue.

If the cable sticks dry hot, it will also stick dry cold.

Yeah, I just don't know how to get to the cable and/or potentiometer....need to take a look. I bought some teflon lubricant at Lowe's that is dry and doesn't freeze or attract dirt.

JDSStudios

I would make sure Teflon does not get into the potentiometer.
You would need (if needed at all) non conductive lubricant.

In my old EE days (80s) we used carb cleaner spray to clean pots, because it evaporated
right after spraying, leaving no residual that would affect the pot resistance.

I really doubt you would need to lubricate the potentiometer.
