I HATE doing the same job twice! I am seriously considering pulling them all and putting new ones in it. Should have done it the first time.

I so feel your pain. I didn't give up right away, I gave the sticks every opportunity to get settled in - the only cost was my time under the hood and my sanity. I'd like to have that time back, but I discovered sanity is overrated.

Did it yesterday. The blue CPS smoothed the idle out somewhat and made the engine more quiet. However, it lost bottom end torque, which is where I normally drive. Havent had time to hook the AE up, (snow and all. Too lazy to go outside) I still had my friendly reminder SES light flashing at me, telling me that all was not well in injector land...Spoke with Ryan and he is sending me out three injectors to swap out.

Cant beat that.
Our weather is going to break next week. Sunny and 50's. The "Truck With No Name" is going into D check. Going to start with a compression test. I'm pulling the engine this spring to do the oil pan and I'm going to overhaul it if it needs it then. Stay tuned.
Sticks, X-codes with zone off road pack, ball joints, rear drive shaft out to get balanced and yoke checked, hubs, unit bearings, all steering linkage, rear springs(left one sagging about 2") and all the parking brake components. Still cheaper than buying a new truck.

Absolutely! His exact words..." I stand behind my product and I want you happy."

I'm going to go on record...that if you find a suitable compression test, your short block rebuild will be minimal. I think of a bigger concern will be the heads. But, "minimal" is a relative term.

If worn poppet seats were a common cause of injector failure, then wouldn't we see a greater number of rejected cores? I'm sure this occurs, but if you're getting your remans from a reputable company, then this shouldn't be a concern. I would hope that during the rebuild process, that 0.004" clearance would be checked, and if it's good, then clearly there can't be injector body wear at the valve seat, right? Couldn't this be something one could easily check (as illustrated in the pdf) with remans right out of the box?
Just my two cents...

This is an interesting comment, although I would argue that if a reman injector had excessively worn valve poppet seats, then the injector wouldn't pass any subsequent testing, and thus not be sold.

I get your point about the .004 clearance, but I just don't know that much about the poppet seat (in the body) and the reman process to speculate. Just repeating what I was told. I did ask if there was a way to remachine the seat, he didn't believe it to be cost effective....I was thinking it would really open up a source of cores.

The dark blue Motorcraft CPS gave me the exact same results. I switched to the grey and I think it contributes to a slight wandering idle I have.
Against all conventional wisdom, I've been thinking of giving aftermarket a shot considering Ford or Int'l could never get this part right.

If wear were an issue, then for this many cycles I think it would occur consistently over time and for all injectors. How many of these injectors have been produced and run for 200k miles, since what, 1994? And how many have experienced valve seat wear? I'm inclined to believe that with proper lubrication and maintenance, the wear on the injector body (valve seat) isn't an issue. The valve itself might be the defined wear item in this assembly.
I'm not saying it doesn't happen, or there aren't other failure modes of the injector body - rejected cores do exist. I'm just thinking that if the builder is a quality guy, and if he considers all of these things, and stands by his product, then I would never question his rebuilds and would happily buy remans. And would gladly do so from your builder.
