What's the usual cause for a squeak kinda noise when you lay off the gas. It does it when you aren't giving it gas and when you aren't moving. It does NOT do it when you give gas.

TRy to do another video in the day and open the hood and try to locate where its a bit later. a black screen and a squeak sounds doesnt help

 

As of right now, I'm just seeing if anyone knows that sound from previous experience. I actually took that video to show my RPM's drop on a cold start, not for the sound, but you can hear the sound pretty good inside.
