2005 FORD F-350 Vehicle Speed Control Problems

I PURCHASED THE TRUCK USED FROM A PRIVATE DEALER IN AUG 2011 WITH 66,000MI. ON IT! FROM THE DEALER THIS ISSUE STARTED. IT HAS HAPPENED AT LEAST 2 DZ TIMES NOW AND FORD REFUSES TO ACCEPT THE ISSUE AS A FORD ISSUE! THEY TELL ME ITS THE TIRE PRESSURE AND I HAVE HAD IT TO THEM 3 TIMES TO FIX THIS ISSUE, THEY HAVE RE INFLATED MY TIRE PRESSURE TO " FACTORY RECOMMENDED PRESSURE" AND WITHIN 5 MILES ITS SHAKING SO VIOLENTLY I HAVE TO PULL OVER AND START AGAIN, THIS WILL CAUSE A DEATH EVENTUALLY!! I WILL NOT LET MY WIFE DRIVE THIS TRUCK AND THAT IS WHAT IT WAS BOUGHT FOR, A SAFE FAMILY VEHICLE. *TR

TL*THE CONTACT OWNS A 2005 FORD F-350. WHILE STOPPED WITH HER FOOT ON THE BRAKE PEDAL THE VEHICLE ATTEMPTED TO SURGE FORWARD. THE RPMS INCREASED EXCESSIVELY AND SHE HAD TO APPLY EXTREME PRESSURE TO THE BRAKE PEDAL IN ORDER TO STOP THE VEHICLE FROM SURGING FORWARD. THE FAILURE ALSO OCCURRED INTERMITTENTLY WHILE DRIVING THE VEHICLE. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE SHE WAS INFORMED THAT THE EGR COOLER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE 39,000.
