Does the car have a check engine light on? You at least need to tighten the belts if not replace it. The MAF is a good place to start checking, any leaks after it and the car will run pretty bad.

well the cars bin throwing altinator belts.. gessing a bad pully. the car sat for like 6 years in a garadge. i went to a junk yard to get a new maf sensor but they sold me the wrong one and a new one is 600$. the car just randomly starts squeeling the belts.

oh yes the lights on

You need to get the codes pulled on the car. Its there too tell you there is a problem so get that checked out and it will give you a direction to start looking in.
