what pushes accelerator pedal back?
 

I've been experiencing a "sticky" accelerator pedal. Got in there and when I moved the linkage by hand and the pedal rod DOES NOT return to "up" position. Went into the back and I get free movement. Opened up the tunnel in front of the back seats and I get the same feel when I move by hand. Tried to feel around in there the best I could and did not feel anything hanging it up.

So the question -- What part pushes the gas pedal back into the up position?

What year is your (I assume) 911S?

Generally there's a spring back at the CIS FI throttle that returns the linkage to the idle position. Probably broken.

The return springs do that. You may have some binding at the pedal cluster linkage or at the trans. It's good to remove the bits and clean/lube them every so often. I don't know that there is an "official" timeframe for this.

Should clarify it is a 76 911S.

In addition to the pedal cluster (likely source), there's also the pivot link attached to the gearbox to inspect.

I've even heard of the driver side carpeting bunching up against the gas pedal.

Among the parts mentioned above also check that the spring on the throttle body isn't stretched or broken

The spring on my gearbox broke approaching the hairpin #9 at Eastern Creek WOT. That was interesting.

It happened again when I replaced it with a hardware store spring, this time at turn 6.

Don't use crap springs to overcome linkage routing/angle issues!

Redundant springs are always a good idea. There's usually two on a flat six intake system, but not on a later MY. Thanks for the reminder.

Rebuild the pedal cluster. Not that difficult, but wow you would be surprised at what a difference it makes. The pedals worked so smoothly after. The pedal cluster is the lowest point on your floor pan and behind the floorboards where you never vacuum, so it's where all the dirt, gunk, and whatever is stuck to the bottom of your shoes over the last few decades has accumulated. I would have to say that rebuilding the pedal cluster was one of the top 10 improvements I have made to my car, everything seemed so responsive after that.

On a side note, the clutch cable and the throttle cables run very close together in the center tunnel, and can interfere with each other, this could also be causing your accelerator pedal to bind up a bit. It's really difficult to get in there and see what's going on, you almost have to be a contortionist from the circus to do it. But if you have ruled out all your springs, try looking at that and see if it that is causing problems. You can also adjust the length of your accelerator cable and the accelerator pedal position to give you more travel if you want.
