on a 2002 cougarHow to change fuel injector?
1. Go to your public library reference section and find one of the Motors or Chilton manuals and photocopy the pages that describe the procedure. 2. Go to an auto or hardware store for EYE PROTECTION AND NITRILE GLOVES. Gasoline is dangerous stuff and also not good for your eyes or body. 3. Make sure you follow ALL of the directions in order. If the directions don't make sense to you, get someone who does know how to do this. It isn't hard in and of itself, but getting all of the stuff off the engine to the point where you remove the injector is a major PITA. One more hint, take many pictures of each step to put it back correctly.
