P0266???

[Greenhorn Diesel]

I was leaving my mother in-law's house yesterday, when I noticed my truck having a little more zip. I didn't think anything of it, untill I was almost home. I checked for codes with the DD. Nothing came from generic but I got 2 from Ford specific. P1000, system readiness, and a P0266 Cylinder 2 Contribution/Balance Fault. I cleared it it, and I could not get it to come back. I will try more today to see if it reappears. Do I have an injector going bad? Hanging open perhaps since the truck had a little more zip? Those were the only two codes that I got.

I would be worried about that. That sort of thing happened on my 6.0l. Obviously it has different injector technology, but it had the same effect. It was pouring black smoke, and it would go like hell. Then, according to the Ford dealer in West, Texas (where it gave out) the fuel injector broke in half. To me, it started pouring enormous amounts of white and black smoke. I am sure it flooded the cylinder with fuel and coolant when it exploded.

If there is any quirk that 6.4's are known for besides bad radiator design it's fuel injectors getting stuck open. If the code comes up again, or if you continue noticing the weird power properties, I would definitely get ti checked by a Ford dealer. You don't want to burn a hole in the piston head.

clear the code and drive it , keep your eyes on it and see what happens

Thanks guys. I hope it was just a quirk in the system, and nothing seriously wrong. I do not feel like putting the DPF back on for the warranty work. I know this problem exists with stock trucks as well, but I don't want to give Ford a reason to void warranty.

I would take it to Ford. It could be nothing but if it is something they will fix it.

I put about 100 miles on it today. I horsed it, and took it easy. Boosted launches, and starting out in 3rd and I could not get it to come up again. I am going to call the Ford dealer tomorrow and see what they say as well

I know why my truck would be having extra zip after leaving my mother in-law's house, but it wouldn't be because of a problem with the truck..

So the P0266 code really means get the hell out away from the mother in-law? That would make sense. I can't get the code to reappear. My dealer called it a computer "gremlin"
