Broken gas pedal for 99 Boxster


Recommended Posts

Hi all,

Never thought this is happening. The accelerator (gas) pedal for my 1999 Boxster is not working.

It's stuck when I tried to push the pedal by foot and the engine is not going anywhere.

The part for the whole pedal assembly is very expensive, over $400, This is the Tiptronic version.

I found a used part for about $59.

Does anyone ever had this happening before? Is it a DIY job?

Anything I need to pay attention if I decide to replace myself?

Thanks.

Steve

Where is it binding up? Before spending money on a pedal assembly, ensure you figure out what exactly the problem is.

First place I'd check is at the throttle body. Make sure the cable didn't slip off to the side there. If so, the butterfly valve won't open when you press the throttle pedal.

Hi,

It's stuck at the pedal. The pedal is not even in straight forward position. The pedal doesn't move at all. If I push really hard to force it, I still can accelerate the engine.

This is bizarre.

Hi, I replaced mine a couple of years ago, its not too difficult. You need to establish whether or not yours has the e gas throttle. I seem to remember that there is a plastic link on the pedal which a ball joint at one end which can become dislodge, this happened on mine so worth having a look first. Its also possible the hinge has broken, I did a temporary repair on mine using a small door hinge. Definitely a DIY job, hope you manage to sort it soon.

Hi,

Thanks for the reply. I got an used gas pedal (part number 98642302708) from Ebay. At the front of the pedal, there is a cruise control module (part number 99661702103) connected to it. BTW, this is a Tiptronic. I think they just give it to me as a bonus. At the back of the pedal, there is a long steel cable.

Is this the throttle cable?

I want to replace the whole brake pedal as a unit and not to fix the old one. Is it easier that I use the old throttle cable and connect to the new pedal?

Or should I use the throttle cable came with the new pedal and replace the old cable that's connected to the throttle body?

Which way is easier?

For the cruise control module, should I replace my working old one with the new one?

This task doesn't look like straight forward.

I appreciate your input.

Thanks.

Steve

Your car is not the e-gas model. You have a throttle cable from the pedal to the throttle body. You'll need to check the cable that is in the car to make sure it hasn't been damaged as a result of pushing hard on the pedal. I haven't replaced one of these so can't tell you any specifics about the process. Do a you tube search - maybe someone has a video posted.
