Gas pedal/ Throttle Cable questions

OK I think I might have stumbled across something that is slowing me down. My throttle cable has been kind of mangled in the engine bay, I dont know what by. Its like the heat stuff around it was cut open and has split. The cable is still functional but I think it has been stretched. I will be replacing this soon.

My question is with the gas pedal. It seems like it is hanging to far forward. In park with the motor at idle, the bottom of the pedal is touching the floor. Is this normal? For some reason I remember it being higher up, closer to the brake pedal's height.

For some reason I remember that if i pressed on the brake while stopping, but had my foot like half on the brake, if i pushed far enough, my foot would hit the gas pedal and cause a jerking motion.

That is impossible now even if i push the brake all the way down. So I think its too low for some reason, maybe when the cable was stretched or whatver happened caused it to be that way. Does anyone have any ideas on how this can happen? Like a bolt loose or something? I dont think its bent but I guess it could be.

Any ideas?

If the pedal is touching the floor while at rest, the cable is definitely stretched or falling out of it's mountings.

Man, that new cable is going to make a HECK of a difference.

I think my cable may also be stretched. My gas pedal isn't as far down as yours but it's farther down that I think it should be. Besides that sometimes my pedal sticks a little when I'm decelerating, I think this might be due to the stretching thing. How much difference will a new cable make? Has anyone priced one?

I have the exact same thing, the pedal looks lower than it should be. It also sticks sometimes, if I rev it it will stick sometimes, and it sticks under deceleration also. I thought it was the throttle sticking, but when I took it to get the differential fluid changed and a guage problem looked at, I had the GM dealer look at it and they said the cable was catching on the carpet or something. I may look into a new cable now. Adam62083, keep us informed

Rather than your cable having stretched, you probably have a collapsed housing. That is consistent with the split cover. The effect is the cable seeming to be too long.

If the cable is sticking, that is an unsafe condition. Fix it immediately.

What do you mean by collapsed housing? I'm not sure I know what you are talking about...

I am not familiar with that either. Can you give me some pointers?

The part that pulls the throttle is the cable, the inner part. On the pedal end, it is pulled into the passenger compartment when you step on the throttle.

The part that clips on the bracket on the engine is the housing. The other end of the housing is mounted to the firewall.

In order for the cable to work, the housing must resist the movement of the inner cable on both ends. A Sir Isaac thing.

The housing is a spiral wound part for flexibility. It isn't uncommon for a seam or two to break somewhere in the housing and no longer properly resist the inner cable movement. Same effect as lengthing the inner cable.

Ok...that makes sense. But in order to fix this, will getting a whole new cable also give me a new housing?
