1994 GMC SONOMA Vehicle Speed Control Problems

DRIVING MY 1994 SONOMA AT APPROX 50 MPH ON A HIGHWAY WHEN ALL OF THE SUDDEN THE GAS PEDAL STARTED TO MOVE AWAY FROM THE BOTTOM OF MY FOOT AND THE VEHICLE BEGAN TO ACCELERATE ON ITS OWN (AS IF THE CRUISE CONTROL WAS TAKING OVER). I THINK THAT I THEN TAPPED THE BRAKE AND THE VEHICLE WENT BACK TO NORMAL SPEED, WHICH WAS TO DECELERATE AS MY FOOT WAS STILL OFF THE GAS PEDAL. I DO NOT USE CRUISE CONTROL, BUT CRUISE CONTROL SWITCH WAS IN THE ON POSITION. I HAVE SINCE SWITCHED CRUISE CONTROL TO OFF POSITION AND DISCONNECTED CRUISE CONTROL MODULE HARNESS, AND WILL LEAVE IT DISCONNECTED.

I WAS ACCELERATING FROM A STOP LIGHT (GOING APPROX 20 MPH) WHEN THE THROTTLE STUCK AND QUICKLY SURGED TO RED LINE. I SHUT OFF THE IGNITION AND COASTED TO THE SIDE OF THE ROAD. THE TACHOMETER WAS PEGGED OUT. I RESTARTED THE VEHICLE AND EVERYTHING SEEMED FINE. THIS HAPPENED ONCE BEFORE (~8 YEARS AGO) WHILE I WAS PASSING ANOTHER VEHICLE ON A RURAL HIGHWAY. DURING THAT INCIDENT I ALSO SHUT OFF THE IGNITION BUT ACCIDENTALLY LOCKED THE STEERING WHEEL AND ENDED UP IN THE DITCH. IT WAS VERY DIFFICULT TO STOP THE VEHICLE DURING THAT INCIDENT BECAUSE I WAS GOING ABOUT 60 MPH AND HAD NO POWER BRAKES SINCE THE IGNITION WAS OFF. I WAS UNHURT BUT THE VEHICLE WAS DAMAGED DURING THAT INCIDENT. I TOOK THE VEHICLE INTO A DEALER FOR INSPECTION BUT THEY FOUND NOTHING AT THAT TIME. I AM AFRAID TO DRIVE THE VEHICLE NOW. *JB
