Speed Control Cable problems of the 1998 Ford Explorer Sport

Driving in rush hour traffic on 4 lane road at 35 mph the accelerator stuck wide open. Immediately jammed my left foot on the brake to not hit other cars while trying to use right foot to get behind the gas pedal and unstick it. Put car in neutral and eventually was able to get pedal unstuck. Checked to ensure floor mat was not causing the problem. Proceeding driving with hazards at less than 25 mph. Within 10 minutes same thing happen except that this time I was initially unsuccessful in getting the pedal to unstick. While waiting for a tow truck, approximately 45 minutes, the pedal popped out of place. Garage has determined that the accelerator cable is defective and needs to be replaced.
