My car is an '02 - I don't know when or how the pedal may have changed for other years.

So I covered the air box opening with plastic (you don't want carb cleaner getting into the air box or on the MAF, etc.), and used a rag with some carb cleaner to clean the inside of the throttle body.

I also used some screws to minimize the play between the pedal and and the base.

If you can move it easily, even though it�s under a lot of spring pressure, then the problem is somewhere between the cable and the foot pedal.

This is making acceleration very jerky and clearly I need to get it fixed.
Hi guys. I have a 996, which I bought two weeks ago from a Porsche dealership as CPO. Today the accelerator started to become very sticky. In other words, instead of the accelerator pedal moving down smoothly, it sticks from one point to the next. This is making acceleration very jerky and clearly I need to get it fixed.
Is anyone familiar with this issue, and what it should cost? Also, shouldn't this be covered by the CPO warranty? If it�s a non wear-and-tear item it certainly should be covered, but even if it is somehow considered to be a wear-and-tear item it still should have been taken care of when the dealership did their comprehensive CPO inspection before I bought the car two weeks ago, correct?
Any guidance would be much appreciated, so thank you in advance to whoever can help me out here.
Best,
Jake
Hi Brad. Thanks for the note. I just checked it out. Unfortunately the floor mat is in the right place and isn't in contact with the accelerator at all, so that's not the problem in this case. I was hoping you were right though. I'm just hoping dealers aren't going to try to make me pay to get this fixed.
Check behind the pedal the best you can. If you have to, use a mirror. Since no one I have read (on 3 forums) has had this problem, it probably is something simple obstructing pedal travel.
My brother had this issue on his 99 C4 CPO. The dealer did not cover it and quoted him around $850 to replace the thing. He had a local independant take the unit apart and clean it and it is like new. Cost around $75 if I remember correctly.
If you bought it 2 weeks ago TAKE IT BACK. They will fix it...call them and schedule an appointment. Dont even ask them if its covered...it doesnt matter, if you bought it 2 weeks ago, have them fix it as a pre existing condition...tell them it did it from day one and got worse....
I've got the same problem on my '02. It's not so bad that I can't drive it, I only notice it cruising on the highway where I'm making minor accelerator adjustments. Please PM me (or update this thread) if you find an easy or inexpensive fix. I guess I could take it apart and "clean it" like TCR's brother had done, if I wasn't afraid of buggering it all up.

Well Jake, although few people apparently have had this problem, I decided to post my solution in case it can help someone else down the road.
My car is an '02 - I don't know when or how the pedal may have changed for other years.
There is one screw holding in the accelerator pedal assembly. Remove this screw. You then need to slide the assembly up about 1/2 inch and then pull it out. You could now disassemble it, but what I did was to slide up the boot (the rubber thingie) that protects the interior.
The way this thing works is that there is a rod that connects the pedal via a ball and socket joint to a half round pivot that is connected to the throttle cable. It's hideously over-engineered, but with the engine in the wrong place I guess it makes sense.
I squirted a little oil on the ball and socket joint and worked the pedal several times. There is also a hole in the back of the assembly, so I squirted some more oil from the backside. There is nothing electronic in there, so there are no worries about oil messing something up.
Installation is the reverse of removal. Except that I had trouble getting the stupid thing lined-up to get the screw back in. You'll figure it out - just be sure to line up the round tab and get it inserted into the bracket. Once I got that, it was fine. Note that it is easier to reinsert the boot before you put the assembly back in the car. That keeps out the dirt that probably caused the problem in the first place.
Now the throttle pedal is nice and smooth.
Good luck!
Michael
Michael,
That worked wonderfully. I took it off night, cleaned it off, added some grease, reinstalled, and the accelerator is now as smooth as silk.
I think a lot more people have this problem than realize it. I tried out the accelerator pedal on a 2002 last week and it had the same issue, yet its owner had no idea. Personally, it drives me nuts not to be able to choose precisely how much gas to apply, but evidently many people just don't notice it.
Anyway, thank you again for the great advice. Much appreciated!

Same issue here. It's not really a sticking so much as a creaking when gradually modulating the throttle. It's annoying as hell. The service guys have been in there twice to lube the pedal to no avail. If you come across a reasonable fix, let me know, please, so I can pursue it.
Hello- I have an '01 996 and the gas pedal is not smooth at all and has became a major annoyance- so much so that I don't want to drive the car. I've asked my mechanic twice to look at it and he didn't have a clue.
The symptoms in the posting are exactly what my car has, and just spent about an hour trying to remove the gas pedal assembly.
I unscrewed the one screw, pulled up the boot on the connecting rod, but couldn't ge the assembly to budge at all. It sounds as if I am to slide it up and then pull it off.. not sure totally if that makes sense since it appears to be connected to the pedal, but perhaps I am missing something. Any help would be greatly appreciated, the car will have to sit until I can get this resolved. My wife complains I am giving her whiplash while driviing. Thanks.
There was a thread here a while back about this. The guy removed a C-clip or something that was binding up the ball and causing the pedal to feel jerky.
He said it made a huge improvement.
You may find the thread with a search.
I haven't tried it but would love a smoother feeling throttle .
I don't remember if these were the threads I saw but found them with a quick search...

The throttle in my 2002 996 Carrera 2 was not very smooth, so I pulled out the entire pedal assembly to clean and grease it. I also used some screws to minimize the play between the pedal and and the base. I was very happy with the results - the throttle no longer feels like an on/off switch, as I am now able to modulate it with much greater precision.
Items needed:
- phillips head screwdriver
- white lithium grease
(optional)
- drill
- 1/16" drill bit (pre-drill)
- 5/32" drill bit (countersink)
- 4x 3/8" long sheet metal screws (McMaster.com #90033A105)
As I was unable to disengage the throttle cable from under the dash, I disassembled the pedal in the footwell. Remove the one screw in the top left hand corner that holds it to the floor and push the assembly up and towards the front to disengage it from the floor.
Remove the 4 screws on the right side to open up the assembly and unhook the cable from the pivot:
Disassemble (the metal rod connecting the pedal from the base will pull right out of the housing with a little force) and wash every part with dish soap and water:
Grease both points where the rod inserts into the pedal/base housings, and the pivot shaft housing. There was some play btwn the pedal and flex joint, so I added 2 screws to affix them together (as seen btwn the 2 plastic clips on the bottom of the pedal):
Assemble as pictured before re-installing:
Reinstall the throttle cable and assemble in the footwell. I added 2 more screws to affix the flex joint to the pedal base:
I had a sticky throttle on my '99 996. After I took apart the accelerator pedal assembly and greased everything up nicely - thanks for posting the pictures, that REALLY helped me - I still had a sticky throttle. Mine was sticky off idle. So that's a TIP: if it's sticky when the throttle is closed, it might be the actual throttle body. I took the air box tube leading to the throttle and sure enough, it was sticky there. So I covered the air box opening with plastic (you don't want carb cleaner getting into the air box or on the MAF, etc.), and used a rag with some carb cleaner to clean the inside of the throttle body. Need help holding the throttle butterfly wide open? A used up cardboard roll from wrapping paper was the perfect length to wedge between the gas pedal and the steering wheel. After manually rubbing the inside of the throttle body, removing the wrapping paper cardboard tube, I then started my car and let it idle. I then sprayed small amounts of carb cleaner into the throttle body.
This completely resolved my sticky throttle issue.
I realize this thread is 4 years old., However, I am facing a similar issue where from idle, the pedal barely moves unless I practically stomp on the pedal. Help!!!
First thing to check is try to move the throttle body valve directly from the throttle body in the engine bay. If you cannot move it from there, with your hand (use a glove and be careful not to get your finger pinched), then the valve is stuck. If you can move it easily, even though it�s under a lot of spring pressure, then the problem is somewhere between the cable and the foot pedal. There is a throttle stop screw that you can adjust if the throttle isn�t resting on the screw. I think it should be resting on the screw, otherwise the valve will be resting on the bore of the throttle body cavity, which is not good and will score it.
Thank you for the reply. I did check the throttle and it is able to be moved by hand very freel. I ran out of time today so tomorrow will check the peddle assembly.
Posted up on Rennlist and Facebook Outlaw Boxster site and someone nailed the problem with the pedal. When I was wiping down the engine or after I started the engine, I blipped the engine from the throttle body and pushed the cable off of the black curved piece on the linkage. Put it back on this morning and everything fine.🤗
