Engine light on, cyl 4 misfire.
I have been running Cobb on and off using various its maps for the past 2 years plus 40000 kms, 2 days ago my engine light came on and my Cobb states misfire on cyl 4. I changed the plugs about 17xxx kms ago and was thinking about replacing my coils now. Any thoughts? When I'm running a tune I use 94 fuel.

You could start with moving coil #4 to #1 and see if the misfire goes to #1.
If it doesn't, I would just shoot another set of plugs at it. I've been tuned for the past 35k km and have been through two sets of plugs (although I think there was something faulty about the first set). I'm at 74k km now and my coils have been pretty solid, although I've been noticing my timing get worse, so it might just be about that time. |

Coils can go bad early. Some last 40k and some last 100k.
