Default Running Lean
Ok I know that it's time to do the plugs and boots again but twice now I've gotten a check engine light and my eve is telling me that I'm running lean on bank 2. Am I. Looking at a possible cat issue?

If your check engine light is on, then you have a code. Have it read by Autozone or somewhere, just don't buy anything yet.
