We are finally diagnosing our GTO. It is time to apply all that we have learned over these last few months. We show many different ways to test for different lean and rich concerns on your vehicle. Ranging from quick and easy to more in depth. At the end of this training you should have a good understanding on how to pursue a rich or lean code.
