Speedo Not Working... Like the title stated the speedo in my friends 99 SS M6 stopped working. Also, the car stumbles and dies when idling. The PCM threw the VSS code but we have changed the sensor and still nothing. We tested the new sensor in my 00 Z28 M6 so we know that thats not the problem. We chased the wiring back to see if there was any breaks or shorts...Nothing. The reference voltage is also good to the plug. At this point were stumped...Any help would be greatly appreciated.
