Sticking Gas Pedal

[SCOOTER52]

Have a 2000 Boxster s with 33k purchased recently. Can anyone give me some info on freeing a sticky gas pedal. Not a safety issue but annoying.

I had a similar problem after I replaced my AOS. The pedal had tons of resistance and then would let go all at once causing a surge. It turned out that the pedal cable had slid off the throttle cam at the top of the engine.

Hope this helps.

No throttle cable a MY2000 - MY2000 on has eGas.

On my 2004 986S, there is a cable that comes out of the pedal and wraps around a cam under the dash that rotates some sort of servo. It is electronic from there. The pedal itself is completely mechanical, and sort of rudimentary.

There is a plastic piece that inserts at the base of the pedal and which rotates on a plastic spindle. Up about 2/3rds of the way, a metal "dogbone" piece comes out of the pedal enclosure and connects with a ball in a base on the back of the pedal. When you press the pedal, it rotates another cam- shaped plastic deal in the case that moves the cable.

The cam under the dash is spring loaded. I would take a close look at that, and the "cam"shaped thing in the pedal, as well as the spindle at the base.

Thanks for your help. I pulled the rubber boot off the shaft connected the the pedal and was able to spray some WD40 (using the red tube provided) into the ball and socket type attachment. This made a big difference but still not as smooth as my 2004 Chevy.

Be sure you check the tension on the cam under the dash - it should be pretty tight - if it is not loaded enough, it will not pull the cable and make the pedal come back up, and if it is not rotating back, it is keeping the throttle open some. Also, at the base of the pedal, it rotates up and down around a spindle. You can't really see it, but it is at the base. Be sure it is not getting hung up down there. There might be gunk keeping it from moving freely. You can take it off, disassemble and clean the hole pedal assembly. Little awkward getting under the dash and disconnecting from the cam, but it can be done and is fairly straight forward.
