Hi Dana:
I never heard of such a thing. If the cam isn't turning, I can't think of how it could run. Many of the cylenders would have had valves open, so they wouldn't have worked and the ones with closed valves wouldn't have gotten any fuel. Plus the cam sensor wouldn't even send a signal to the ecm so it shouldn't have been getting spark.

You got me stumped.
