If it has a carberator check to make sure that the throttle linkage is in a relaxed position when the car should be idoling in other words if the linkage is too tight then while your gas pedal may not be pressed the linkage is so tight that it is still pully on the throttle linkage and causing it to rev. The only reason i can think of it revving on its own though is maybe a tension spring on this linkage is broken and the linkage is loose and flopping back and forth from idel to throttle with bumps and other distrubances.
