Car is misfiring badly, the E85 fuel is probably 2 months old and am getting codes 29E0, 29E1, 29F1, 2A2C, as well as shadow codes 2AAE, 2FA3. Let me know if this points to anything suspicious to you. Strangely came a while back, then disappeared, and is back again. Haven't driven the car much as I'm in the process of moving but have some time for the next few weeks.
