After owning my 84 GN for 2 weeks the famous "Service Engine" light came on. Reading through the ScanMaster it appears to be a Malfunction 22. TPS is reading low. The TPS on the ScanMaster is at 0.00. I believe thats what the number was when I got the car. I bought a Volt Meter and tested the connection. I got a reading of nothing. The Volt Meter did not catch anything. Could there be something wrong with the TPS or the TPS Connector? Or am I not using the VoltMeter correctly? Can someone post a picture of their TPS? Also, what alignment are the spark plug wires with the spark plugs?
