Please do I am intrested in what you find out.
Because I was under the impression a faulty knock sensor would through a code because it's so important.
If it does not code when bad I'm getting mad at Ford again.

OBD-I will not throw a code for the knock sensor. And I'm not completely sure that OBD-II in the V10 will either.
Again, it only pulls 4 degrees of timing - if there are enough other contributing factors, it might not be enough even with a working knock sensor.

My 2012 Motorhome E450 V10 has the same problem
It only has 26,000 miles on it. I've seafoamed it twice with little change. Of course being a motorhome, it's always under a load. I'm watching this thread with interest

As the first owner for the truck for the for short while he had it was ironically a State trooper that deleted the cat I very much doubt that that is the problem, lol and I'm not particularly thinking it's a fuel issue with how it's reacting?

Yes it is only with a load, even at low speeds. But I have checked the flexplate and changed the transmission oil (dropped the pan a couple of times) and it is clean as can it can be..... Time for diagnostics isn't happening now, corn has been planted but now I'm working on switching to soybeans.

If my math is correct I only have around 21 million corn plants in the ground now... kind of mind-boggling but I am honestly a rather small farmer.
