2000 7.3 liter intermitant issue

My son has a 2000 7.3 psd (of course) HE cleaned his air filter. (K&N) and a few days later, he said his truck fell on its face, idled rough, blew black smoke... barley made it home. He shut the truck off, then restarted it, and it ran fine. he replaced the fuel filter to be safe. He went out that eve, no issues, then the next day he has the same symptoms. There is no ryhme or reason, no running time parralels. It just starts stumbling and a small amount of black smoke out the exhaust. Also when the issue is hapening, the check engine light comes on yellow. When it runs fine, then engine light goes off.... HE did have is Camshaft positioning sensor done by Ford a while back.... I might add, his programmer is Edge (Juice with attitude) But, he isnt chipped up while the issue is happening.

I think the Airfilter is coincidence.... I told him to start checking wiring, and clean the grounds.... But I am not a diesel guy. Any help or direction would be appreciated...

It is probably under the valve cover plastic connector that controls the injector and glow plugs has come loose... see the following thread for more info.. and how to fix it.. (reading the fault codes would help)

Like Clint said, have his codes read and we can have a better idea what is going on.
