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.
If your 2003 Grand Am accelerates without pressing the gas pedal, the throttle plate may be stuck.
Found out that I had an exposed wire lying on the arm of the gas pedal.
NO. It has a cable.
kick down cable is stuck
Shift to reverse

Next to the gas pedal
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.
That's what the gas pedal does.
