Start with wiring. Unplug the VSS, with a jumper wire, touch one end on the connector and the other end of the jumper wire on the other connector,
have someone turn the ignintion key key in "start"and watch the speedometer moves anytime you touch the jumper wire en on the connector.
If it is acting up as it is doing now, then the problem is in the wiring or the back of the needle need lubricated
if it act up better, then the speedometer gear is strip, remove the VSS and check it out.
