1986 Porsche 944 4 cyl Two Wheel Drive Manual
it was running great and then it cut off suddenly. Let it cool a bit and it starts right up for around 5 or 6 min. Then dies. Replaced plugs, wires, coil, dist. Cap and rotor. Also thermal sensor. Fuel checks out by book, and also air flow sensor, and 2 sensors at rear of engine. Any help? Noticed that it had no spark after cutoff. It will spark the moment I turn the key to crank, and then one spark when I let go of key.
