Where to start? Well, I would want to know where the self adaptation values are. You will be able to see those if you use a scanner such as the Baum CS 2000 or the AST Retriever.

Once you have those numbers, I will be able to help you with the fuel trim problems. The percentage numbers mean nothing to me, we use the adaptation numbers that are based off of the Stocheometric (sp?) efficiency standards.
