Solution for "sticky" throttle?

I have a 2002 996 with 18K miles on it that I've owned for 6 months now. The car is in great shape and runs awesome, with one annoying little "nit": at very light throttle in stop & go traffic, the accelerator seems to "stick" mechanically. A very light press and it won't move, then it will break loose and move. This isn't enough to cause engine surging, but you can definitely feel it and it gets pretty annoying. The car has an e-throttle linkage, so presumably it's just the pivot mechanism at the pedal itself. I have tried to put some grease in there and have also asked a garage to fix it (Chris' German Auto - don't get me started with them). Any advice? Has anyone else had a similar problem? Thought you'd also like to see my car - these are pictures from the dealer I bought it from. The car is in the same shape now. Attachment 313394 Attachment 313393 Attachment 313392

Welcome to Rennlist. nice looking P-car! Have you cleaned the thtottle body? That can get gummed up a little and stick, causing rough idle.

Welcome - Nice Car!! (I live in Bellevue, so near you?) There is another idea, hard to tell from how you described it BUT if it happens while operating the clutch in and out, there is a switch that can be responsable for that. It is a maroon colored one up on the clutch arm, it comes out with a 1/4 turn and can be taped "closed" and tucked back up in the wire harness. some people say that makes the throttle feel better for them, I tried it and went didnt like it because I became "used to" the other way. Had I done it right away when i first got the car, I would have kept it that way. someone might be able to find a thread on this, it takes only <5 minutes to do and might be worth trying... free, and if it does nothing, put it back Any other mods you have done? (muffler by-pass? just curious if I know the car or not)

I don't think the clutch thing is related. I happens without any clutch operation. Thanks for the idea, though. I have noticed that switch: it clicks sometimes. In terms of mods, I have only owned the car for 6 months. It's almost bone stock, although it has a lot of equipment on it - kinda' what attracted me in the first place. Current equipment: Aero pkg, fixed rear wing (not on car originally; added later), carbon fiber steering wheel, shifter & brake, full leather, supple leather, advanced technic, porsche crests in seats. I live in the Puget Sound region of WA (eastside), but purchased the car through Columbia Valley Luxury Cars in the Tri Cities.

Welcome to the Forum. I am also a Puget Sound area owner. When I added aluminum pedals, I ended up with a problem that is not too far off from what I think you are describing. Behing the gas pedal in my 2001 C4, there is a little metal stick with a ball on the end. It rests in, but does not snap into, a circular area on the back of the pedal. The excess weight of my aluminu pedals can cause it to spring back harder than the OEM pedals and the little stick can become misalinged. This can cause me throttle problems similar to your description. I haven't found a perfect solution but am currently use a bit of blue tac adhesive to hold the little ball in place on the back of the pedal. So, you may just want to feel behind the pedal and see if the little stick is in the right spot. Regards, Scott

Thanks, Scott. I'll take a look and see if that's the root cause. Appreciate it! How do you like your aluminum pedals? I've been thinking about getting them 'cause I think they look great. Any advice on doing it - or not - and brand?

I bought the $99 set off ebay that say "Porsche" and have the little rubber nubs. They do look good and I like them, but not at the expense of the throttle issue.

The accelerator pedal on my 2001 C2 has gotten very sticky. I’ve read the many posts on this subject, including removing the pedal and cleaning the hinges. My question is looking on the back of the pedal there is a round ‘boss’ that I am guessing the ball on the end of the ‘stem’ (rubber boot covers most of it) should fit into. The ball is larger in diameter than the boss on the pedal and is usually not in the right spot when I inspect. I have not found a diagram showing how these two items fit together and would appreciate any ideas. I am am open to replacing the pedal assembly and would be interested in thoughts from those that have done so. Thanks, Pat

Maybe you need a new pedal assembly? Did you see this post and read the embedded posts? https://rennlist.com/forums/996-foru...gas-pedal.html

Mine was sticking at the throttlebody. Have you checked that area before talking the pedal apart?

You might have to pull the pedal out and check the movement. From this diagram, the e-gas pedal has the cable that comes out of the top and goes to the pedal sensor. So that cable might be binding, or the pedal sensor is binding. On the e-gas, the pedal sensor transmits the electrical signal to the throttle body, so more than likely it is not the throttle body binding. http://www.autoatlanta.com/porsche-p...section=702-10
