Is the rough idle consistent with cold or hot engine temps? Valves, chain, ip timing, I think, would cause constant problems hot and cold. I would suspect filters first, injectors second. Try cracking injector lines at idle and see if idle is affected. If idle is consistently rough when an injector line is loosened, switch that injector with another and see if the problem follows that injector. But you should check the other things mentioned as well and post back.
