what motor 2.4L or 2.2L?
1. could be a timing chain or a waterpump (I'm thinking chain tensioner though), depending on the motor.
2. car is old enough, check the Cat, it may be getting plugged up
3. light in the radio burnt out, old car, it happens, no replacement that I know of, buy an aftermarket stereo, and enjoy the better sound.
4. the price of a motor, around $75 IIRC, and an afternoon with a Haynes manual replacing it and the rivets.
theirs a nice writeup on
www.j-body.org on the windows, in fact you can get a LOT of answers there. as well as find some good upgrades and what not.
