Need some Help new to 6.0 Surging while Under Load Issue
Hey guys I have a 2006 F250 6.0 with 198k heads redone with new gaskets around 150k. Heres the issue runs fine at idle does fine. If you brake stand slightly its slow to build power wont even brake the tires free. And when driving under light to heave load it feels like its missing like lack of fuel or bad injectors? No codes for injectors. Replaced fuel filters still the same. Like i said it idles perfect, and light load mainting it drives fine once you get into the gas or going up a hill it bogs and feels like it missing. Any help would be great also when its doing this there is no white smoke from the tail pipes, just at times slight black smoke or light blue.
