This is my best friend's truck.
2006 F250 6.0l manual transmission (six-speed L+1-5). 180,000 miles. Fairly recent purchase. Unknown maintenance history. Has one of those ZillaRaider(?) six-setting performance gizmos on it. Is supposed
to have "EGR delete" but the EGR
valve looks to be on the engine like in the pictures, so IDK (how do you tell?). Had no exhaust after the cat
(was for sale separately) but my buddy had a single "straight-pipe" exhaust put on from the cat
back. Did oil/filter and fuel filters (both) change right after purchase.
He turned the gizmo knob down to 2 or 3. Still ran great. Not "race car" great, but "better drop a gear to pass this old coot that's going 40 in a 55mph zone while there's a little bit of straight road - oh <BLEEP!> we're going 100" great (lol).
Engine light came on. Had it scanned at GenericAutoCrap (I think it was an O'Reilly Auto Parts) and was told EGR
valve. Figured it needed to be cleaned, was waiting on Spring (now waiting on Spring... weather) to do so. Still ran great.
Couple weeks ago he said sometimes if it's fully warmed up and he shuts it off and tries to restart it within a couple minutes, it "takes more cranking than it should." But still ran great.
He's working 12-hour shifts about 1½ hours from here, so he got one of those campers you stick in the truck bed (NOT a pop-up, hangs over cab). But campground has been deserted for the Winter, said with no television, no Internet, and no people he felt like he was in solitary confinement, lol. So today he asked me to ride up with him in case he needed a hand to bring his camper back; he's going to drive back and forth for a while. No problem, it fit on his F250 fine.
We weren't in a hurry, so he just set the cruise on 85. Heading back south on the Interstate... He said, "Hey, man, what's this wrench light on my dash mean? That's new." And then, "Wow, my cruise dropped to about 70 and it never does that, it's always within a mile or two." And then...
We got passed by some guy in a Toyota Prius!!!
For a while, there, I was afraid I was going to have to post in the "Roadside Repairs" forum.
About ten minutes before the thing went all geriatric on us I had asked him if the camper was slowing it down any and he said, "No, only way I can tell it's on there is that it rides better." Go figure.
Anyway, I looked in his owner's manual as we limped down the big road and - appropriately enough - read that the wrench icon on his IP signified that the truck had gone into "limp-home" mode
We got back to town and stopped at another generi-parts to have it scanned. Here are the codes:
P0401 "Exhaust Gas Recirculation Flow Insufficient Detected"
P2290 "Injector Control Pressure Too Low"
P0299 "Turbo/SuperCharger Under Boost" (Guessing that one should read "Insufficient Boost," since it's a turbo's job to be "Under Boost"
After the scan, he started it back up and no wrench. It ran fine on the way to drop me off at my house. But he's really worried about trying to drive it to work tomorrow night and doesn't have another vehicle available. So he could really (, really
) use some help on this. Internet-based brain type help would be a big help all by itself, but if you're in the Parkersburg, WV area and know these engines, I could give him your number (or vice versa) since neither one of us is a mechanic, lol.
Thanks (MUCH!) in advance!
