Symptoms:
- Rough idling or engine misfire
- Reduced engine power and acceleration
- Increased fuel consumption
- Engine warning light illuminated
- Excessive oil consumption or oil leaks
- Overheating or coolant loss

Diagnosis:
- Check for faulty ignition coils or spark plugs causing misfires
- Inspect the intake manifold and EGR valve for carbon buildup leading to rough running
- Scan the ECU for error codes related to sensors such as MAF, oxygen sensors, or camshaft position sensors
- Examine valve clearances and timing chain condition for wear or slack
- Inspect for oil leaks around valve cover gasket and oil pan
- Test coolant system for leaks or thermostat malfunction

Fixes:
- Replace worn or faulty spark plugs and ignition coils
- Clean or replace the EGR valve and intake manifold to remove carbon deposits
- Repair or replace malfunctioning sensors identified by diagnostic codes
- Adjust valve clearances and replace timing chain or tensioner if stretched or noisy
- Replace gaskets causing oil leaks and top up or change engine oil as needed
- Repair coolant leaks, replace thermostat, and flush cooling system to prevent overheating

Prevention:
- Follow regular maintenance schedule including timely oil and filter changes using recommended oil grade
- Use high-quality fuel to reduce carbon buildup in intake and valves
- Periodically clean the throttle body and EGR system to maintain airflow
- Replace spark plugs and ignition components at manufacturer intervals
- Monitor coolant levels and condition to avoid overheating issues
- Address engine warning lights promptly to prevent further damage
