Does anyone have or know where I can find a vacuum hose diagram for a 99 burb 7.4L 454? I think I may have a vacuum leak somewhere but I don't know where. I just changed the plugs, wires, cap and rotor...runs great but after it warms up and i'm stopped, idle tends to drop occasionally and feels a bit rough. Thanks in advanced!

Autozone didn't have any vacuum diagrams that I could find. Good info on the vehicle otherwise. You might try purchasing a chilton CD. They're usually only about $21.95 or so.
