It has been my experience that an engine, while "dieseling," often runs
backwards. This can be observed while it is occurring. This means it is
running on combustible gasses from the exhaust system being drawn back
into the engine. As such, no disconnection of the ignition system or use
of an anti-run-on valve will stop it. This is also why applying full
throttle doesn't stop it.
You can test for this by placing the transmission in fourth gear and
letting out the clutch; if it's running backwards, the car will lurch
backwards.
Running backwards is not good for an engine, since the oil-pump will be
drawing lubricant away from the bearing surfaces.
