My friend's Del Sol has a speedometer problem. The speedo doesn't read accurately while accelerating or cruising at speed. If he goes ~65 or thereabout, the speedometer reads 20 mph. I replaced the vss the other day with a spare I had from my old GSR and it still does the same thing. I assume the problem is in the cluster but I'd like to know if it can be repaired rather than replaced, due to the rarity and cost of the gauge cluster. Thanks a lot fellas.
