Hello,
As I was driving the interstate to work this morning I noticed my speedometer was around 20mph high. When I came to my first stop. I turned off the truck and started it back up. The needle sat at 20mph at idle and while turned off. Today at lunch she was sitting at 5mph so I pulled the DIC fuse and put the truck into ACC mode, then replaced the good fuse and started her up ("trick" I found online). That didn't seem to make any difference. I drove it up the block and back and it remained at 5mph over, and thats where it sits now. Any tips or ideas as to how I can fix this myself? Thanks!
