It is much easier to learn how it works and then let it work for you...
I'll spare you the heap of negative comments I normally have for this type of work...
Here's a book that will get you started with how the Ford electronic engine control or "computer" works.
Ford Fuel Injection & Electronic Engine Control 1988-1993 by Charles Probst :ISBN 0-8376-0301-3.
It's about $30 from Borders.com see http://www.amazon.com/ . Select boo... so I thought I would pass it the info along.
