I missed that. Question is, was the engine really varying that much
or was it something else? The EM2 gets tach info by watching the primary
injector switching. If the injector drive was erratic that would make the
tach go wacky. John said controller A & B worked the same so
I ruled out controller problems. An intermittent connection to
the injector would fit the symptoms though.

heat-soaked coils?
John Slade's observation included info that the EM-2
was showing wild
swings in RPM. Is this a clue to the problem?
I'm not sure coils
failing would take out the tack info. Is
there another failure mode
that could cause the tack to malfunction and
the engine to sputter -
crank angle sensor failure, bad wiring
connection from the EC-2 to the
coils?
