07 6.0 cutting out at highway speeds
First of all I know there are other threads with similar symptoms..and I've spent a month reading everything I find. I have an 07 6.0 with only 62,000 miles that is driving me insane with this problem. This truck ran fine until the fuel gelled up once, even with power service additive, temps dropped drastically and all hell broke loose. While driving at interstate speeds of 50+ it will randomly act like it's cutting out or surging, let off the gas and let it do it's thing and it will come back within a few seconds like nothing happened. It doesn't do it every day but when it decides to, it will surge 5 or 6 times and then carry on fine. It only does it at highway speeds, never while driving in town. I should also mention since it's now female owned it doesn't get beat or haul anything. It has been to Ford 3 times, and a individual garage in the last 2 months and I have spent a small fortune replacing parts that "may" be the problem. The only codes the truck has thrown is for 3 of the injectors and the EGR. If anyone on this planet has some advice I would appreciate it. New parts..all new injectors, IPR, new fuel filters, fuel pump, air filter, cleaned egr, ebp sensor cleaned. The truck doesn't have many upgrades, just head studs. No tuner, no EGR delete or the other bulletproofing upgrades..yet.
