Maybe you can get something out of this:
http://www.autozone.com/servlet/UiBr...ginRepairGuide It's not quite as good as a manual but, it might give you something to go on.
You can get a Haynes or Chilton's manual at just about any automotive store ie, Autozone, Pepboys etc for $15-20. I think even WalMart sells them. I would have thought some honest sole would have explained the pitfalls of sinking money into a 14 year old car especially to someone in your situation. Sad to say but, this happens far too many times.
I've found small family run automotive shops that have been around many years to be the most reliable. Their reputation is far more precious to them since they don't have a huge automotive giant to fall back to.
Keep in touch.
