I have a 95 teg and i just put in a new gauge cluster because my old one the speedometer was 8 mph over the normal speed. Also i put new gauges on the cluster. When i drive the car sometimes ill be going like 40 mph and all of a sudden the needle will jump to like 60 mph. Does anyone know what the problem could be? Could my speed sensors be messed up?
