Vehicles using FA24 engine list:

Engine FA24

Symptoms:
- Rough idling or stalling during cold starts
- Excessive oil consumption or oil leaks
- Check Engine Light (CEL) illumination with misfire or sensor fault codes
- Reduced engine performance or hesitation under acceleration
- Unusual knocking or ticking noises from the engine

Diagnosis:
- Perform a thorough visual inspection for oil leaks around valve covers, gaskets, and seals
- Use an OBD-II scanner to check for stored trouble codes related to ignition, fuel delivery, or emissions systems
- Conduct a compression test to assess cylinder health and detect potential head gasket issues
- Inspect ignition coils and spark plugs for wear or damage causing misfires
- Check for carbon buildup on intake valves, which can affect performance and idle quality

Fixes:
- Replace faulty ignition coils or spark plugs to resolve misfires and improve combustion
- Repair or replace leaking gaskets and seals to prevent oil loss and contamination
- Clean intake valves using professional walnut blasting or chemical cleaners to restore airflow and smooth idle
- Address any detected head gasket leaks or cylinder compression issues with appropriate engine repairs
- Update engine software via dealership to fix known ECU-related issues and optimize performance

Prevention:
- Use high-quality synthetic oil and adhere strictly to recommended oil change intervals to reduce wear and deposits
- Avoid prolonged idling and allow the engine to warm up properly before heavy acceleration
- Regularly inspect and replace air filters to ensure clean airflow and prevent contamination
- Follow manufacturer-recommended maintenance schedules, including spark plug replacement and fuel system cleaning
- Monitor engine performance and address minor issues promptly to prevent escalation into major repairs
