FICM going out?
I just bought a 06 6.0 and after having it 4 days it started to sputter around 55-60 mph. Then it would slow start like the batteries were going dead.
First chance I got I took it in and got an oil change, & fuel filters changed.
While it was in I had them check the voltage on my batteries. Turns out I had a bad alternator. New fuel filters did not help the sputtering.
Sputtering only happens when accelerating at normal speeds. When I "get on it"
it doesn't sputter. No smoke, just a sputter. Could the low voltage from the bad alternator have damaged my FICM?
