To diagnose engine sputtering:

Check for Error Codes: Use an OBD-II scanner to read engine trouble codes that can pinpoint sensor o r system failures.

Inspect Spark Plugs and Coils: Look for signs of wear, fouling, o r damage and replace if necessary.

Fuel System Inspection: Have the fuel injectors tested and cleaned if clogged.

Air Filter Check: Ensure the air filter is clean and replaced regularly.

Look for Vacuum Leaks: Inspect hoses for cracks o r disconnections.

Sensor Testing: Have the mass airflow sensor, oxygen sensors, and throttle position sensor checked for proper function.
