What trouble codes do you have? This is an OBD I vehicle so you can get the codes using a paper clip. Jim

Try ebay or Faxon Auto Literature, they have a website, for a factory shop manual that will explain how to get the trouble codes out of it. Unfortunately, without the codes, you're just going to keep throwing money and parts at it. Jim
