Accelerator pedal issues

[Autonomy_Lost]

Since I've gotten my M998 I've noticed the accelerator pedal is pretty stiff. It ends up making the engine feel underpowered because you really have to jam on the pedal to get decent acceleration.

I've already checked and lubricated all the linkages at the top of the engine (sorry don't know the technical terms) and they feel totally fine. It seems to be an issue with the pedal itself.

Today I took a closer look and I noticed some issues where the pedal linkage goes through the firewall. There is a bushing assembly there. Its a triangle shaped plate with 3 bolts holding it to the firewall. The bushing appears to have some play in it, but also the entire firewall seems to flex slightly when you press on the pedal. Who the heck designed it like this? The firewall is very thin and flexes under the slightest bit of pressure. That combined with a slightly worn out bushing results in the pedal linkage (I'm talking about the rod that comes from the pedal, not the cable) rubbing on the firewall.

Anyway, what's the best way to fix this? Buy a whole new pedal assembly, or just replace the worn bushing? Is there anything that I can do to reinforce the firewall to remove some of the flex?

Did you undo the cable and make sure it moves freely? The 2 plastic bushings in the firewall are just a couple bucks.

Might want to lube the cable also

When I got my M998 a few years ago I dealt with the same thing. My girlfriend said my right leg was getting bigger from having to push the pedal. I started a thread on here and most everyone said its not like a regular modern pickup etc.... So last month I needed a project and bought the whole pedal assembly (23$) ? and accelerator cable. Its made a big difference. I now have full travel resulting in being able to get full power out of this beast . Took only an hour or so with a helper. The TM was a big help.

Good luck

Thanks for the info, I think I'll go ahead and do the same thing.
