Engine CSA7153

Symptoms:
- Rough idling and occasional stalling
- Reduced engine power and acceleration hesitation
- Increased fuel consumption
- Check Engine Light (CEL) illumination
- Unusual engine noises such as knocking or ticking

Diagnosis:
- Inspect ignition system components including spark plugs and coils for wear or damage
- Perform a fuel system check for clogged injectors or fuel filter issues
- Scan for diagnostic trouble codes (DTCs) using an OBD-II scanner to identify sensor faults
- Check for vacuum leaks or intake manifold gasket deterioration
- Evaluate the condition of the exhaust gas recirculation (EGR) system and gasoline particulate filter (GPF) where applicable
- Assess timing chain tension and camshaft timing for irregularities

Fixes:
- Replace worn or fouled spark plugs and faulty ignition coils
- Clean or replace fuel injectors and fuel filter to restore proper fuel delivery
- Repair or replace faulty sensors such as oxygen sensors or mass airflow sensors as indicated by DTCs
- Seal vacuum leaks and replace intake manifold gaskets if necessary
- Service or clean the EGR valve and GPF to prevent clogging and maintain emissions compliance
- Adjust or replace timing chain components if timing issues are detected
- Regular oil changes with manufacturer-recommended grade to prevent engine wear and maintain performance

Prevention:
- Adhere strictly to scheduled maintenance intervals, including spark plug and fuel filter replacement
- Use high-quality fuel and engine oil to reduce deposits and wear
- Periodically inspect and clean the air intake and EGR systems to avoid clogging
- Monitor engine performance and promptly address any warning lights or unusual symptoms
- Avoid prolonged idling and aggressive driving to reduce stress on engine components
- Ensure timely servicing of the GPF system to maintain emission standards and engine efficiency
