    I'm guessing it's your timing belt or the belt on the alternator. Needs a tune up.

    There's no timing belt and it could be many things. Do you have a check engine light on?

    No! I do not have a check engine light on. it would be nice if i did, that way i would look up a code.

    Just because the light is not on doesn't mean that it has no codes. Get it scanned by a real scanner.
