1999 Toyota Camry

I HAVE A "1999" TOYOTA CAMRY THAT ON THE WAY TO WORK YESTERDAY HAD THE ENGINE BEGIN RACING AND THE BRAKES WERE BARELY ABLE TO STOP IT. I HAD TO PUT THE VEHICLE IN PARK WHILE THE ENGINE CONTINUED TO RACE. I GOT OUT AND CHECKED FLOOR MATS AND WORKED THE GAS PEDAL BY HAND AND THE ENGINE CONTINUED TO RACE. I SHUT OFF THE ENGINE AND TRIED RESTARTING IT AND THE ENGINE IMMEDIATELY BEGAN RACING AGAIN. I MANAGED TO MOVE IT OFF THE ROAD AND INTO A GAS STATION AND HAD SOMEONE FROM INSIDE COME OUT JUST TO WITNESS IT AS I COULDN'T BELIEVE IT WAS HAPPENING. I OPENED THE HOOD AND MANUALLY WORKED WHAT I CALL THE THROTTLE CONTROL AND WAS ABLE TO ROTATE IN BUT THE ENGINE CONTINUED TO RACE. ONLY TURNING THE ENGINE OFF WOULD STOP THE RACING. I REPEATED THESE STEPS AT LEAST 3 TIMES AND UPON THE LAST ENGINE START UP THE ENGINE IDLED NORMALLY. I HAD DRIVEN FOR A SHORT TIME BEFORE AND I FEEL CERTAIN THAT THE SPEED CONTROL WAS CONTROLLING THE SPEED UNTIL I TOOK IT OFF. AT FIRST THOUGHT MY BRAKES WERE BAD AS THEY WEREN'T STOPPING THE CAR WELL. THEN I NOTICED IT WAS ACTUALLY ACCELERATING ON IT'S ON. I UNDERSTAND THIS WAS NOT SUPPOSED TO HAPPEN ON THIS YEAR OF VEHICLE AND THAT IS WHAT THE LOCAL SERVICE PEOPLE TOLD ME WHEN I CALLED THEM. HOWEVER, I AM VERY WARY THAT THERE IS AN ELECTRONIC ASPECT TO THE PROBLEM AND EVEN IF IT IS SOME OTHER PROBLEM KNOWN OR NOT KNOWN TO TOYOTA IT IS A VERY DANGEROUS PROBLEM TO HAVE AND NEVER TO HAVE KNOWN ABOUT MYSELF. *TR
