This morning I took the cold air intake apart and adjusted all the fittings and made sure everything was tight. Took it for a spin and same noise. If I smoothly upped the Rpm the sound never showed up. If I romped the throttle it showed up. I'm confused. I guess turn the radio on and hope for the best.

Engine is moving under load and causing a moving part to come in contact with something?

Moving part inside the engine or something rattling under the hood?
