Running crazy lean from low fuel flow or pressure can cause significant backfiring as well.

Huh... I didn't know that. I know these motors run rich from the factory though. All the resistance values when checking the AFM are in spec though. So I doubt the AFM is cause a lean/rich problem. Not entirely sure how old the o2 sensor is. Probably gonna replace it this weekend too because its only like $25.
