ITS MAGIC!!!! :)  really the crank sensor picks up the small deflections =
in
the crank when a misfire occurs, because there is a crank AND acm sensor =
and
notches in the flexplate and cam gear the computer "knows" where each =
piston
is at all times, so when a misfire occurs the crank "slows down" =
slightly in
relation to the cam and the computer detects this as a misfire.

A friend of mine has a 97 Plymouth Voyager. He had a check engine light. =
A
code reader said it was #6 cylinder misfire. I'm curious how that is
detected. Anyone?
