2006 Cummins RAM 2500 shortbed. No aftermarket installations on it. Started up normally, put into reverse and after a few feet went to full throttle by itself and had to back it into a snow bank to stop and shut off the ignition. According to the local dealer, there are no codes and says there is nothing they can do. I bent up the bed and snowmobile trailer tounge during this exciting ride. If anyone else has experienced this, please let me know. Now in contact with Chrys. corp about it.
