Diagnosis:
- Use an OBD-II scanner to read fault codes related to ignition, fuel injection, or emissions systems.
- Inspect ignition coils and spark plugs for wear or damage, as misfires are common causes of rough running.
- Check for vacuum leaks or intake manifold issues that can affect air-fuel mixture.
- Perform a fuel system pressure test to ensure proper fuel delivery.
- Examine the turbocharger system (if applicable) for leaks or malfunction.
- Verify battery and hybrid system health in S E-Hybrid models, as electrical faults can impact engine performance.

Fixes:
- Replace faulty ignition coils or spark plugs to resolve misfires.
- Repair or replace damaged vacuum lines or intake components to restore proper air flow.
- Clean or replace fuel injectors to ensure efficient fuel delivery.
- Address turbocharger issues by repairing leaks or replacing worn components.
- For hybrid models, service the high-voltage battery and associated electrical components as needed.
- Update engine control unit (ECU) software if manufacturer releases relevant fixes.

Prevention:
- Follow the manufacturer’s recommended maintenance schedule, including timely spark plug and filter replacements.
- Use high-quality fuel and engine oil to maintain combustion efficiency and engine lubrication.
- Regularly inspect and maintain the hybrid system components in S E-Hybrid variants.
- Avoid prolonged idling and aggressive driving to reduce engine stress.
- Keep the cooling system in good condition to prevent overheating-related damage.
