Any updates? Just curious if you fixed the issue?
Have you verified the coils are good?
Look into the crank position sensor.
Yes, issue was E85 as I initially had thought.
YES E85 is probably the issue for my 2011 which I ran E85 had a rough idle issue until I changed back to normal 87 gas nor she purrs like a kitten.
A part of me wonders if it's the sensor in our trucks. I had reached out to blackbear tuning to ask them if they could make an e85 map or tune around the issues, and they said we'd have to install a physical sensor in our trucks. Stock, it's a "virtual" or something or another type of sensor, so it's not actually detecting the proper alcohol content.
Currently I switched gas stations to another blend of E85 and my truck fires up first time and drives smooth. I honestly just prefer it over 87 octane, even with the poorer fuel economy.
