Engine Performance problem
1992 Oldsmobile Toronado 6 cyl Front Wheel Drive Automatic 170000 miles
My 1992 Toronado Trofeo dies after it has been running for about 20 to 30 minutes. If I let it sit for 30 minutes it will start but die again shortly there after. I get a code 17 (Spark Refernce Signal). I have replaced the Ignition module, the PCM, the Fuel pump and fuel regulator. I have also replaced the Cam sensor. I have checked wiring harnesses for ware but have not inspected them closely. I did connect a dual trace scope to the ignition module inputs and outputs and I can see that I loose the fuel enable signal when the car dies. I do get pulses from the Cam and Crank sensors when cranking the engine during a no start condition.
Can you provide an answer to this problem before I replace anything else.
have the same problem?
