Weird metallic ringing sound at idle, goes away w/ throttle blip

[Woodsy0]

When I'm at idle, my car makes this really odd high-pitched metallic sounding ring. If I blip the throttle, the sound goes away, but when the RPMs come back down, the sound comes back. I opened up the hood and manually manipulated the TB to try to pinpoint the sound, it seems as if it's coming from the fusebox/airbox/upper intercooler piping area...I have DejonTool intake and upper IC pipes, which may be a factor in the problem, but really I have no idea how to pinpoint and fix the problem, and it's getting really annoying idling around town with a weird ring coming from my car. Any input would be appreciated.

Thanks,
Scott

Is there anything touching the metal piping? A cable or wiring harness tapping the pipes may make a musical kind of tone as it bounces against the tubing.

I've had a couple of funky noises from stuff moving around at idle that went away with a few rpm's.

My cars kind of a pile..and idles a little rough at times..so I've heard a few extra sounds that are but a sweet harmony measured against the lifter tick, and exhaust leaks etc..that make up the usual underhood soundtrack....

Haha, I actually just made a boost leak tester a couple weeks ago, never got around to actually testing for leaks...That's probably what it is, I'll let you know after I test.
