The engine control module has detected a misfire specifically in cylinder 2. This means the air/fuel mixture in cylinder 2 is not igniting properly.
Cylinder 3 Misfire Detected
The engine control module has detected a misfire specifically in cylinder 3. This means the air/fuel mixture in cylinder 3 is not igniting properly.
Cylinder 4 Misfire Detected
The engine control module has detected a misfire specifically in cylinder 4. This means the air/fuel mixture in cylinder 4 is not igniting properly.
