Why stock gap with a 1) Blaster SS coil (48k volts) and 2) Digital 6
ignition. This may not solve your problem but I would gap your plugs out to
.050. You have an extremely hot spark with an extremely long duration. I
would still change your before the cat O2 sensor.

The oxygen sensor is suspect, but doesn't that usually trip a mil light?
I've got 58,xxx miles on her with no O2 sensor change outs.
Plugs are gapped at stock spec.
l've had all these mods on during warm weather and all of them except the MP
SK-250 last winter with no problem.
