I recently bought a 93 del sol si and I'm slowly trying to fix this bad boy up. Anywhoo the speedometer is wayy off and sometimes it doesnt even move. when im going maybe 55 it reads 20 and doesnt go anywhere past that. I was thinking maybe its the vss sensor, but im not to sure. I pulled out the cluster recently and made sure all the wires were plugged in correctly. The odometer, temperature, and all the other gauges work fine. Does anyone know how i would diagnose this problem?
