Sounds like a problem with the power valve actuator in the intake manifold collector. I would check with a Nissan dealer first and inquire of any recalls or service bulletins. Might save ya time & money.
Take a look at Nissan Technical Service Bulletin NTB05-15b. Title = "Rattle Noise From Vias Power Valve Actuator / Intake Manifold Collector" This appears to describe your problem exactly. I have the same problem with my 2005 Xterra and I am going to try the recommended fix myself at home.
