I just got back from Auto Zone and my engine light sensor spit out 4 codes. Code 1- 522-Selector Lever position sensor; Code 2- 113-Intake air temperature sensor; Code 3- 176-Oxygen sensor-mixture too weak; Code 4- 543-Fuel pump circuit. Does anyone know what I need to do about this? I just bought this car not even half a year ago and I've already had to replace the alternator... what next?
