Oxygen sensor failure - Loose fuel cap - Catalytic converter failure - Spark plug/ignition coil issues - Bad spark plug wires - Mass airflow sensor failure - Issues with an after-market alarm - Vacuum leak - Exhaust gas recirculation valve failure - Dead battery
My check engine light is on. Now what? Get it checked by a professional ASAP.
Best bet, regular maintenance to help prevent the check engine light to come on in the first place.
