what coudl cause this noise
So i get a buzzing rattling noise when i hit about 4200 RPM. Sometimes it makes ths noise sometimes it doesnt. I notice when i hear that noise i notice a slight loss of power, like my car isnt pulling as hard as it should be, but im still going. I have a 93 LS Auto. Suggestions please.
