Read forums, webpages, get some magazines, etc.
And most of all if you really want to do repairs, try to get an official Ford repair manual for that car, not the Chilton's, although Chilton's will do if that is all you can find.
They will help you learn the basics. The more complicated stuff takes experience and learning from someone that knows it, hands on type stuff.
And it would probably help to get book on the basic working of a combustion engine. Once you understand the basic principles, it will make understanding and finding trouble easier. Anytime you have trouble with your car, you start with the simplest/cheapest solution no matter how lame it may seem, then work your way up. No sense in spending hundreds of dollars on new injectors only to find out you were out of gas.
Car Clueless, Help me change that?
