The vehicle is misfiring (based on the codes) and a common cause of the misfiring is a faulty engine management sensor. The solution to a problem such as this relies on a "diagnostic decision tree" that is set forth in the Service Manual. For the particular codes you recorded, that decision tree implicates the following as "potential" causes: spark plugs, low cylinder compression, damage or excessive wear of spark plug wires and/or coils, faulty fuel injectors, clogged EGR valves or tubes, burned valves, improper ignition timing, vacuum leaks, leaking head gasket, faulty camshaft sensor, faulty crankshaft sensor, faulty mass air flow sensor, faulty oxygen sensor, faulty throttle position sensor, faulty catalytic converter, and others.
