Thread: Any ideas on a car security system?

everything you said sounded reasonable, except:

>>If the mixture in the cylinders is lean enough, you can get

I don't think the knock sensor causes the engine to shut down -
it is just one of the feedbacks the engine control computer
uses.  Typically the spark advance would be reduced in
response to knocking.
