- Check the spark plugs and spark plug wires for wear or damage. Replace them if necessary.
2. Fuel Filter:
- A clogged fuel filter can restrict fuel flow and cause the engine to sputter. Replace the fuel filter if it is dirty or clogged.
3. Fuel Pump:
- A weak fuel pump can also cause fuel starvation and sputtering. Check the fuel pressure to see if the fuel pump is providing enough pressure.
4. Air Filter:
- A dirty air filter can restrict airflow to the engine and cause it to run lean. Replace the air filter if it is dirty.
5. Mass Air Flow (MAF) Sensor:
- A faulty MAF sensor can provide the engine with inaccurate air flow readings, which can cause sputtering. Clean or replace the MAF sensor if it is dirty or faulty.
6. Oxygen (O2) Sensor:
- A faulty O2 sensor can also cause the engine to run lean and sputter. Replace the O2 sensor if it is faulty.
7. Ignition Coil:
- A faulty ignition coil can cause the engine to misfire and sputter. Replace the ignition coil if it is faulty.
8. Throttle Position Sensor (TPS):
- A faulty TPS can also cause sputtering and hesitation during acceleration. Clean or replace the TPS if it is dirty or faulty.
9. Vacuum hoses:
- A vacuum leak can affect engine performance and cause sputtering, check for vacuum leaks and repair them with new vacuum lines or sealing.
10. Catalytic Converter:
- A clogged catalytic converter may have increased restriction, limiting air flow causing loss of power and the sputtering sound, consider its inspection.
