I have a 1990 Integra RS, 5MT. I had to remove the dash to replace the heater core. In the process of removing the instrument cluster, I pulled the end off of the speedo cable where it attaches to the Speedometer. It was fairly rusty anyway, so I replaced the cable. Now I have everything back together & running, but my speedometer goes round & round like a clock. Any thoughts on the problem. Do I need a new speedo? Keep in mind, this is a mechanical speedometer, not electronic.
