Title: Almost useless for all but simple tasks
Review: I bought this book right after I bought my '91 626. The book was great until I needed to do some troubleshooting with it. The time I wasted trying to follow this book full of incomplete, misleading information wasn't worth spending. I should have taken it to a mechanic who had the real information. Nowhere in the book is there any mention of a throttle position sensor. DON'T BUY IT.
