SPEEDOMETER PROBLEM

Nissan Altima

I have a 1993 Nissan Altima GXE with 127,000 miles. The Speedometer is showing 20mph when idling and jumps to 30 or 40 with slight touch of gas. Is this aproblem I can fix myself? If so how do I do it?

Need to scan the PCM first to see if it sees any failures in the system. Aside from a wiring problem you should be able to do it yourself
