Symptoms:
- Rough idling or engine misfire
- Loss of power or hesitation during acceleration
- Check Engine Light (CEL) illumination
- Increased oil consumption or oil leaks
- Unusual noises such as ticking or knocking from the engine
- Reduced fuel efficiency
Diagnosis:
- Use an OBD-II scanner to check for stored trouble codes related to ignition coils, fuel injectors, or turbocharger performance.
