F-250 Bogs Down/Hesitates
I just bought a 1-year old F-250 with the 6.0 L turbo diesel. It was a lemon law buy-back. The former owner had complained that the truck hesitated or bogged down going up hills. The dealer that bought it at auction swore that the problem had been fixed either by replacing the turbo or by replacing a computer chip on the truck. He even took it camping himself to see that it was fixed.
This past weekend I took the truck for its first real road test. It drove beautifully... except: I was coming home on a gravel road, driving up hill (towing nothing). It bogged down or hesitated several times. I would push the accelerator halfway down, but it slowed to a crawl, as though it was getting no fuel.
Any thoughts? So far, this doesn't seem to happen on a level straightaway or going down hill. I drove it on hard top coming back through the mountains, also no problem. It's almost as though, when I'm on loose gravel heading uphill and the wheels start to slip a bit, I get no fuel to the injectors.
Any help would be appreciated. This is my first diesel and I really know nothing about them. But, I'm starting to worry that my lemon is, well, really a lemon. Thankfully, it's still under warranty.
