Yeah, you have any way to see your ethanol content sensor?Anybody running e85 ever have it throw codes? Just put my second tank of e85 & got p0174 & p0171. Lean on both banks. Idol isn't rough & truck runs down the highway fine.
It's common for the virtual sensor procedure to read much lower ethanol than whats actually in the tank.
it might only read 20-40%E despite it actually being 70%+.
Mine actually ready about 60%E when it was closer to 75+ for months and no codes, didnt realize it was incorrect.
Then it finally dropped to reading 40% and threw a lean code.
Tried the "run a few tanks of regular gas through it to reset it" didnt help. Tank after that reported 20-30%.
Filled up on gas again and used the tech2 to reset it, still no luck after.
Ended up putting a physical sensor on it and no issues since.
