1990 Nissan Stanza 4 cyl Two Wheel Drive Automatic 139000 miles
I've just recently purchased a 1990 Nissan Stanza from a friend. I noticed that the speedometer was not working. It would remain at 0mph and sometimes would jump straight to the speed being traveled, and other times would jump from 0 to 100 mph. What could be the problem? What should I change or add?
