2. Oxygen Sensor Testing
A faulty oxygen sensor can trigger the engine light and lead to poor fuel economy. Replacing it restores proper air-fuel balance.
3. Mass Airflow Sensor Check
This sensor monitors how much air enters the engine. If dirty or damaged, it can cause stalls or rough idling. A cleaning or replacement fixes the issue.
4. Spark Plug and Ignition Coil Repair
Bad spark plugs or coils cause misfires and shaky performance. This is a common reason why is check engine light is on, and replacing them can restore smooth driving.
5. Catalytic Converter Evaluation
The catalytic converter reduces harmful emissions. A clogged one triggers the engine light on and affects acceleration and mileage.

7. Fuel Injector Cleaning or Replacement
Dirty injectors can lead to poor fuel delivery, affecting performance. Professional cleaning brings back efficiency.

Leaks in the exhaust can change the oxygen sensor readings and cause the check engine alert. Repairing leaks prevents bigger issues down the road.

Sometimes, the engine light indicates transmission faults. Addressing these early can avoid costly auto repair later.
