Does that have something to do with the problem?
Any coil codes?
Misfire location codes are not reliable. I was getting #2 and #4 but the problem was in #1.

I never said they were, but can be an indicator of a bad coil before you pull plugs to check compression/valves. I got lucky last month on my kids z02 S60, #5 code was #5…but no guarantee.
