Does the theft light come on when you turn the key to run? It should come on then go out. Does it? Have you checked fuel injector pulse?

Sounds like a stuck open egr valve or a severe vacuum leak. These trucks are notorious for a piece of carbon holding the egr valve open causing this exact symptom.
