If the engine RPM's increase when the gas pedal is floored, you have a transmission problem or a problem with your shift cables.
If the engine RPM's don't change when the gas pedal is floored, you have a throttle pedal cable problem or throttle body problem.
You will need an experienced mechanic to diagnose this problem as it is very dangerous to operate the vehicle under these conditions.
