Background:
So I'm chasing a very intermittent misfire dtc that that I don't really feel. Sometime pops up as random sometimes pops up as cylinder. 2. Never during wot. Only after cruising.
My ignition system has new everything minus coil pack so it's first thing I test. Resistance at primary is 1.1ohm from 1 to 3 pin and 2 to 3 pin. Book calls for max .9
Secondary coil tests fine at 13.4 for 1 and 4 and 2 and 3.
Question is this enough out of spec to cause this phantom misifire?
This is a 6 bolt with 2g cas and kiggly crank sensor (to retain stock 2g wiring)
