well it could be a few things but most likely you belt is sliping. That is very common and happens to all cars over the years if the belt is not changed. You should check it out. The belt could be bad but it could also be a bad pully. If you dont know what these parts are look them up on google. its very simple

There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.

Sounds to me like a dry, loose or worn serpentine belt. With the motor idling, lightly spray the serpentine belt as it's spinning with WD-40 or other oil based lubricant (Don't spray near the alternator). If this doesn't work, turn the mortor off and check the tension and for cracks or worn spots. The brakes will not squeal when you are completely still.

with engine off check fan blades and shrould (plastic around fan) for cracks or if loose also check tailpipe bent at end if you backed into something. also check air filter box to make sure its tightly shut.
