New to the forum hope you guys can help me out. I have a 2008 f350 6.4 that I recently bought. Was running great and decided to do oil change, radiator flush, rear end fluid change and fuel filter change. Drove well after tune up. A week after tune I felt it miss twice driving down the road but never did anything else. A week later it randomly shut off going down the road but fired right back up. Did that twice. Changed the cam sensor hoping it would fix it. A week later died at an intersection had to have towed home. Got it home and it fired right up. Lost to say the least. Could I still have air in the fuel system from a couple weeks ago?
