Misfire on quarter throttle as 3000 rpm approaches. Can get way into the RPM range if I’m very gentle on the throttle. My observation is the AFR starts to get rich as 2800RPM approaches, unless Im light on the throttle. Misfiring starts at about an AFR of 10 and I’ve seen it dip to 8/9. In both these logs I observed both a hard mis at 3000 as well as above once I increased throttle. No mis and AFR around 14 with very light throttle
