    Hey guys,

    I am about to put a bullet in this truck. I have replaced just about everything there is to replace to get rid of these codes and they still pop up and the truck runs lean. Any body have a clue what I can do to get rid of this issue?

    So far I have installed a brand new intake manifold w/gasket, new 02 sensor, new mass air sensor, new coolant temp sensor, and just about everything else on the engine.
