VERY Violent Misfiring HELP!

Ok so every once in a while my engine misfires so violently to the point where it will jerk the truck forward while I have my foot on the brake. It's even stalled out on me one time. Lately it's been doing it a lot more often, so i took it to a buddy of mine who works on 7.3s and he said it's probably just the UVCH. So, i looked up some videos on youtube of 7.3s with problems with the UVCH and none of them seem to run anywhere near as bad as mine does when it misfires. I was wondering if anyone knows what I can do to diagnose the problem or if anyone had ideas of what it could be. Thanks.

Physically inspect your UVCH and I bet you will find your problem. It's not that difficult to remove your valve covers.
