High Pitch Noise from Engine Bay During Idle??

[coop.5ohhh]

Anyone know what this is? I’m normally very productive at figuring this stuff out but I’ve come up short here. Anything would honestly help. Just looking for some direction. I’ve linked a video of the audio. Don’t know when it showed up but it’s only when idling. This is a 2017 GT btw with performance pack. Only has a gt350 intake and headers for engine mods.

Hello; Sorry the audio skipped some. But I did not hear a high-pitched noise.

If it is coming from the passenger bottom of your engine, it could be your AC compressor. I would listen under the hood to see if it is topside, down low, left, right etc.
