My 1987 Buick GN has the 145 MPH Speedometer. The MPH jumps around while I am driving and is not very accurate. It tends to stick on a speed for a bit as well (stays at 30 or 35 even though I am going faster or slower than that). Also, the odometer does not work, neither does the trip. Any suggestions? Do I need to buy a new one? Thanks.
