Nope. 2017 5.7 FFV... 11k miles. Never had a drop of E85. Been doing this on and off for 3 months. Thought it was bad fuel but then I started googling and found lots of problems on older models. Surprised to see my 17 is affected. Haven't read the ODBC alcohol percentage yet but I bet it's not 10 like the fuel in the tank...They must have fixed this for good. Just getting to freezing and my Tundra fires right up.
This is a video of it taking 3 tries to get it actually fire. It's about 40* out when I took this a few days ago.
Going to the dealer in 2 days.
Stored trouble code of 'P1604 - Startability Malfunction.'
YOU THINK?
