NEVER EVER pull wires off like this, for a couple of reasons. One is the reflected high voltage pulse can destroy ignition systems.
The second reason is that the fire can "crossfire" and lead you down the wrong path as to what cylinder might be missing
Rather, use a shorting probe to SHORT the voltage on each cylinder. You need two hands, one with the probe and one with insulated pliers. Pull the wire up out of the dist, and as it comes up, insert your grounding probe
A timing light won't tell you squat, especially with MS systems
HAVE YOU checked the wires and the plugs, or changed them?
