I've got an '08 with an intermittant engine power/surge issue. The truck is a CC SB auto with the 6.4. It's been to the Ford at least 3 times for the same problem but the truck doesn't throw any codes for the mechanic to troubleshoot with. Basically the truck runs pretty good but on a frequent occasion is starts to surge and lose power. As an example, you may be at 65mph when it does this and you maintain speed but have no extra power and can't accelerate. The truck surges when you put the pedal down. From time to time when I start the truck to leave the house or a store or something the truck will stall and die but start back up and run tip top. Anybody have this issue or something similar that I can bring to the mechanic. Camping season is just about to start up here in AK and I use this truck normally to pull my 5th wheel. I'd like to have it ready for the season.
