Riding on the back of this question, I am having a speedometer problem. It rests at 40mph, when I am under 40, sometimes it will register the correct speed. However, anything over 40, unless I hit a bump (which is common on New Orleans streets), the needle remains @40mph. When it does pop into place, it will register the correct speed for 5 minutes, then go back to 40. Any suggestions? I know I am probably going to have to have it checked at a shop, but does it sound like a fuse issue, or maybe a wire connection that just needs to be firmed up?
