Sorry to disappear like that, folks, but we had an ice storm that took us offline for two weeks! We also suffered without power for 6 days, but I'm here to tell you not having 'net access was worse!



No, the problem persists. I did some more diagnostic work; I hooked up a timing light on each of the plug wires, pointed it at a wall, and watched the pulses. I can see the misses, and they occur on all cylinders (though they seem to happen more often on #2 and #3). With the replaced coil and wires, this suggests that the igniter is bad since it's the only thing in the circuit which hasn't been replaced.

Unfortunately, the FSM has no procedure to check the igniter, and my impression has always been that an igniter either works or it doesn't; I've never heard of one failing intermittently. Just in case, I have a new one on the way, but would appreciate any insights on this.
