If the air flow is not as specified, then you may have the wrong cold air intake for your vehicle. The code you got for the O2 sensor does not make sense, but if it goes away after putting it back to normal, then you may need to disconnect the battery after installing the new intake, and then see if the computer works okay. The intake may need special programming of the ECM with a chip programmer to work correct.
