Hello...I've been searching through the forums and can't seem to find the answer to my problem. I have a 91 camaro and it seems that everything on my cluster seems to be working except the speedo. Also i noticed that the RPMs are unusually high all the time even when idle. Apparently my year doesn't have a speedometer cable but a sensor. So i took it the mechanic and the sensor is fine but he seems to be stumped. Has anyone else had this problem or the know the solution? Any help would be greatly appreciated. Thanks!
