Actually Tach can cause miss. Engine diagnostic machines are hooked to "tach"
connection (negative primary side of ignition coil) equivalent to "points"
connection. Machines are then able to perform a "power balance test" by
automatically shutting down one cylinder at a time to see how much this
causes the engine to slow down. If tach reading does not drop, that cylinder
is not firing.
