I have a chirping noise sounds like it’s coming from my idling pulley but I’m not quite sure when I rev it up in RPM it goes away but at idle it chirps could use some help(98 camaro ls1)

 

Could be either of the idler pullies, or either of the tensioner pullies, or either of the belts. All three are common sources of this type of chirp. You can remove either belt to isolate the noise to one of the two belt systems as a first step.

 

Or the front bearing of the alternator
