Symptoms:
- Rough idling and hesitation during acceleration
- Loss of power or reduced engine performance
- Check engine light illumination
- Unusual engine noises such as ticking or knocking
- Oil leaks around the valve cover or head gasket area

Diagnosis:
- Inspect for vacuum leaks and intake manifold gasket condition
- Perform a compression test to check cylinder health
- Scan for diagnostic trouble codes (DTCs) related to ignition, fuel, or emissions systems

Fixes:
- Replace worn or cracked vacuum hoses and intake manifold gaskets to restore proper air-fuel mixture
- Repair or replace faulty ignition components such as coils or spark plugs
- Change timing belt and associated tensioners at recommended intervals (typically every 100,000 km or 60,000 miles) to prevent catastrophic failure
- Replace valve cover gasket and camshaft seals to stop oil leaks and prevent contamination
- Clean or replace the mass airflow sensor (MAF) and throttle body if dirty or malfunctioning

Prevention:
- Adhere strictly to the manufacturer’s maintenance schedule, especially timing belt replacement
- Use high-quality engine oil and change it regularly to maintain proper lubrication and prevent sludge buildup
- Regularly inspect and replace air filters to ensure clean airflow
- Avoid prolonged idling and aggressive driving to reduce engine stress
