Have been getting constant lean codes. Mechanic could not find any vacuum leaks. New 02 sensors, fuel filter and air filter. Before I throw more parts at the problem, could someone find any clues in this freeze frame?

I have never seen freeze frame data that included banks 3 and 4, especially when your vehicle only has two. Did you change the correct 02 sensor? Did you roll with a factory one? If not I would check there.
