I just lately discovered that my local library had a book on exam questions that people take to get their ASE certification.
This book has a lot of useful troubleshooting info, but it's not arranged in that order. Still, if you can wade through the questions and answers you may find exactly your symptoms and the cause.
There doesn't seem to be a generic troubleshooting book for cars, except for two volume sets that cost $600 and are vehicle-specific.
Motor's and Chilton's used to publish books along this line but these companies might have become victims of the Internet.
I buy my $25 Chilton/Haynes manuals for my vehicles, before I need them.
My truck has done the same thing for almost seven years, I was told what you are saying ...they checked and everything was OK. I then heard that the programming was updated and they just change an e-prong and all is well. I never bothered to get it changed, I only drive down hills now, seems to work ...
