engine squeak at higher rpms

in between 4500-6500 the engine may or may not make a sqeak or a chirp that i know is probalby not good, sometimes the squeak is like half a second, oher times itll just squeeeeeeek thru the rest of the rpm. what could this be?

also the quick squeek can happen during the decline of the rpms

Squeak or chirp? Hmm...may be a lose power steering belt, alternator belt, ect. Or it might be that you have a vacuum leak. My cold air used to squeak pretty bad cause I had a vacuum leak. Check to make sure your intake manifold nuts are secure. They tend to loosen up and that would also cause a squeal or chirp. Just some ideas it may be something else. Hope you get it figured out.

sounds like a belt
