The lean condition may just be a side effect from the backfire. When you clear the codes and do the CASE relearn, I'm guessing it will go away on its own. If not, you may have 2 unrelated issues, but don't fret about that until you try the above first.

No the engine is stock internals. Has shorty headers and a cold air intake on it. I will search for the CASE relearn and see if that helps me out. Thanks for info!
