Sigh... I think you are right shiv, but I'm going to at least run this tank out to make sure the higher ethanol content isn't causing all this weirdness. Is there anything else that would cause LTFT's to jump around? DI seals, Intake leaks, etc? Logs coming home from dinner look semi fine to me on the highway. LTFT is a tad high but stable. The one pull I did getting on the highway had AFR's in the low 12's this log.
