Engine squeals at part throttle
If I'm just cruising (say @ ~2000RPMs) and increase throttle just a bit, I hear a squeal from under the hood. It's not like a belt squealing though, it's more like a brake rotor squeal. It goes away by increasing or decreasing throttle just a little.
Anyone experience this?

Check the rubber hose connections on the intake. On my dad's, the bottom part of the rubber hose connecting to the throttle body wasn't sealed up and caused a slight air leak that would make a whistle sound at the exact same RPM and would go away with an increase or decrease in throttle.

Re: Engine squeals at part throttle (5 Liter Eater)
Hey.. My Z06 whistles. I wonder if your squeal is like my whistle. I'm crusing around at usually 2500 rpm, and when I press on the accelerator just a little bit I hear this whistling sound, just a little more press on the accelerator, or depressing it makes it go away. It's kind of like when you take a hearing test. I've taken it to the dealer twice and they can't hear it. I even drove them around for a 5 minute spin. It's so frustrating...
Let me know if someone figures this out..
