I have a Flex Fuel 2008 F150 with a 5.4 that has intermittent long crank and about every 20 cranks when cold I get a misfire code.
Cant see where I can check the Flex fuel inferred% or FF-INF% to check the ethanol content of fuel in the tank versus FF-INF with the OBD car doctor
Also I cant see where the Flex fuel learned: yes/no or FF-LRN with the OBD car doctor
These PIDS should help me understand how the PCM is perceiving the fuel blend after a completed learn.
