Sounds like a belt problem!! Remember, you have TWO belts. Remove the belts for a short drive and see if that takes care of it!!

Squeel when accelerating
Dad's car has this strange squeel coming from the engine when you accelerate. It only happens between 2000-2500 rpm's. Nothing below or above it. I've checked all the intake connection points and they are tight and there are no leaks. It sounds alot like a throttle body spacer type squeel. Any ideas? Thanks for the help yall.

When you say squeal I think that's a bit misleading - do mean squeal like a slipping belt or maybe a high pitched whistle?
If you have a high pitch wistle, it is most likely related to the intake manifold. There is a small cavity on the inside of the intake manifold near the throttle body that results in a whistle at some RPMs and certain throttle position (certain air flow).
This is much more noticable with an aftermarked filter/intake (more air).
I had it on the '01 and again (less) on the '04. There is a mod to fix it but it entails plugging that cavity and if I remember right was too involved for me to just eliminate a little whistle.
Without hearing it in person, this is my guess based on what you've described.

It is a whistle. Yellow01, do yu know of a link or something where I might check this out? Someone told me it may be a pulley or something going out (like the bearings or something).

Here's one that describes what you are hearing - I guess the intake whistle was only '01.

If the whistle changes pitch with rpms, it is either the throttle body whistle (common on 2001's like mine) or the alternator bearings are toast. To check the alternator, simply remove the serp. belt for it and rev the car a couple of times. If the problem goes away, replace the alternator.
