I have a 95 gsr in my 93eg and sometimes the speedo starts bouncing and then about a minute later the check engine light comes on. I bought a speed sensor on ebay and installed it but it doesn't look like the same one I took out of my car. I can't tell if it's going to work aleast for the next 3-4 weeks because my motor is in the process of getting rebuilt and upgraded. Any help on this subject?
