Featured Check Engine Light Products at AutoZone S Gen McMulen

  • Mass Air Flow Sensor
    This part makes sure the correct amount of fuel is delivered to the engine. If you’re experiencing rough idles or stalls you may have an issue with this part. Duralast MAF Sensors are designed to meet OE specifications.
  • Oxygen Sensor
    A faulty or bad oxygen sensor won’t properly regulate the air-fuel ratio in your engine, resulting in rough or irregular running. This can affect engine timing. If you’re getting an oxygen sensor error code, replace with one from AutoZone for confidence in OE-equivalent quality.
  • Canister Purge Valve
    Maintain a high quality of fuel vapor with a high-quality canister purge valve. A bad canister purge valve can cause difficulty starting or rough idling and will usually cause your check engine light to come on.
  • Catalytic Converter
    A key part of the fuel efficiency of your vehicle. If this fails, you may notice a sharp drop in gas mileage. AutoZone carries replacements that comply with emissions standards for the federal government and the State of California.
  • Spark Plug
    Spark plugs ignite the air-fuel mixture in your engine to keep pistons pumping. AutoZone carries OE and better quality spark plugs for high performance and long life.
  • Ignition Coil
    Ignition coils send power to the spark plugs and make them ignite. Bad or faulty coils can cause stalling, backfiring, strange noise coming from the engine or low engine power. Replace with coils from AutoZone for confidence in OE-quality performance.
  • Spark Plug Wires
    Complete an ignition tune-up by replacing wires at the same time as spark plugs. You’ll ensure a solid connection and moisture-tight seal for maximum performance.
  • Thermostat
    If your engine is overheating or showing rapid temperature shifts, you may have a thermostat problem. Avoid expensive engine damage by replacing with an OE or better thermostat from AutoZone.
