Dead Injector only at Elevation??
I was up on PikesPeak (10k-14.5k feet) a few months ago for the races. During practice, when I would be atleast 12k+ feet and sit there off for 3-5 hours, after starting the truck, it sounded like a piston was going to bust through the engine when under power. During idle/engine breaking (downhill, low gear) it was fine. And once I got to a lower elevation, it completely disappeared.
I am guessing the piston sound is an injector not working. But what does it mean that it only happens at elevation? There is air stuck in there? Leak? Weak injector?
**This is after driving 2,000 miles from SanFran.
1990 F250 7.3 with Aftermarket ATS 093 turbo.

I live in Denver, and drive at 12k' frequently, and I can tell you that it is not a normal thing. You see a lot of black smoke at elevation, but I have never had those kind of problems.
