1989 corvette speedometer problem
I have a 1989 Corvette that the speedometer just started acting weard. It started jumping and will not work properly. I replaced the VSS and made very little difference. It would show higher speeds when slowing down. Just replaced the Instrument Cluster because it had other problems but did not help, still no speedometer.
Is there something else that would cause this?
Please Help

Make sure the VSS is correct for the tooth count of the driven in the car. There are 2 different pitches. There's a VSS for 39 or less tooth count and another for 40+ count.
