If the gas pedal is sticking on a 1980 Chevy, it is possible that the cable is wearing out. Check for slack in the cable. There could also be dirt on the pedal itself that is causing it to stick.
Broken or disconnnected cable, something stuck under pedal,
I suspect that the linkage between the gas pedal and the throttle is worn. Check the cable that connects the two.
Found out that I had an exposed wire lying on the arm of the gas pedal.
NO. It has a cable.
If your 2003 Grand Am accelerates without pressing the gas pedal, the throttle plate may be stuck.

To replace the gas pedal in a 1998 GMC or Chevy van, start by disconnecting the negative battery cable to ensure safety. Remove the trim panel covering the pedal assembly, then unbolt the gas pedal from its mounting bracket. Disconnect the throttle cable or electronic connector, depending on the model, and install the new gas pedal by reversing the removal steps. Finally, reconnect the battery and test the pedal for proper function.
Either your gas pedal is stuck to the floor or you are going downhill.
If you are traveling at freeway speed, (with the gas pedal stuck it might be faster) NO, unless you had to, to avoid hitting an object or person. The reason is, you would blow your engine by stopping so suddenly at such a high speed. If you do find your gas pedal stuck, first try to get it up with your foot. If that doesn't work push as hard as you can on the brake. (just because the gas pedal isn't working doesn't mean the brake pedal isn't) It WILL eventually bring your car to a stop, but slowly. Pull over to a curb or roadside as you are braking, turn off the engine and get the gas pedal fixed.
