Symptoms:
- Rough idling or stalling
- Loss of power or poor acceleration
- Engine overheating
- Excessive oil consumption or leaks
- Check engine light illumination

Diagnosis:
- Inspect for vacuum leaks around intake manifold and hoses
- Check timing belt condition and alignment; worn or slipped belts cause rough running
- Test coolant system for leaks and thermostat operation to address overheating
- Examine valve cover gasket and oil seals for leaks
- Use OBD or scan tool to read fault codes related to ignition or fuel injection
- Perform compression test to assess cylinder health

Fixes:
- Replace worn or damaged timing belt and tensioner to restore proper timing
- Repair or replace leaking gaskets and seals to prevent oil loss
- Flush and refill coolant; replace thermostat and radiator hoses if faulty
- Clean or replace idle air control valve to stabilize idle
- Replace faulty ignition components such as spark plugs, coils, or wires
- Address vacuum leaks by replacing cracked hoses or intake manifold gaskets

Prevention:
- Follow recommended maintenance intervals for timing belt replacement (typically every 90,000 km or 60,000 miles)
- Regularly check and maintain coolant levels and condition to prevent overheating
- Use quality engine oil and change it at specified intervals to reduce wear and leaks
- Inspect vacuum lines and gaskets periodically for signs of deterioration
- Keep ignition system components clean and replace spark plugs as per schedule
- Monitor engine performance and address issues promptly to avoid further damage
