Losing Power around 55 mph Early Model 2004 6.0L
Hey yall, wanted to see if any of you have experienced something similar. My truck runs, drives and idles fine. But I when I hit about 55mph I lose all power. 45mph fine. 50mph fine. Above that and it goes gutless and the power gets all fluttery and drops out.
Im going to replace all my fuel filters and pull the HFCM for a rebuild and clean out for starters. Sorry i dont have any Gauge data. I didnt have a scanner in the truck at the time.
