My 06 F350 is dead. Driving to Chicago, it ran fine for the first 600 miles, then, in St. Louis, it lost power going up hills. Got to the point where it would barely move with the pedal floored. I limped into a gas station and got online looking for answers. After about 20 minutes, I started it, ran better, so I went to the nearest Ford dealer. He ran a scan and there were two codes - one for a glow plug and one for exhaust gas recircle. I knew about the glow plug and figured I'd worry about it when the weather got cold. I'd recently cleaned the EGR, but figured that was the problem. But, it was running normal again after cooling off a bit, so I started down the road again and made it all the way to Chicago without a problem although I could feel a little miss at times. Once I got off the highway though and started driving through town, it started missing worse. Finally died and wouldn't start. Let it sit a few minutes, it started, and I limped into a Ford dealer.
Bought and installed a new EGR valve and thought that fixed it. Ran great for about 10 miles, then started missing a little, and then died. Sat on the road a few minutes, it started up again, and I limped into a parking lot.
What else could it be?? Any help? Replacing the EGR seemed to help a lot, so I assume it was bad, but what else would go out at the same time?
BTw, I had just changed the oil before leaving on this trip and noticed the the oil filter cap wasn't completely tightened down, I think it loosened up. Would that affect anything? Didn't see any leaked oil and I've tightened it again now.
Sorry to be so negative but my original thought here is that if you don't get it going and gone by sundown you won't have to worry about messing with it at sunup. Leaving the most stolen truck in America in a parking lot in the 'Windy' running or not makes me cringe.......they're not stealing them all to resell at used car lots. Dead in the water there is still a lot of used parts there. Can't help you with your engine problems but good luck, I hope all works out well for you and keep us posted.
