I've changed fuel injectors, fuel rails, plugs and plug wires, coil packs, and the fuel filter.... The truck started messing up about a week ago, the top end is knocking, not revving up, not goin over 35mph, and rough ideling..... Any help?
Light knocking almost sounds like an exhaust leak but it's not...
 
Have you checked the fuel pressure? A 2001, I noted you changed the fuel filter, but, without looking at it my self, and from what you describe, is either low fuel pressure or maybe a jumped timing chain. You never mentioned how many miles on the car. Not much info to help, so this is a guess.
