Engine ANX

Symptoms:
- Rough idling and occasional stalling
- Reduced engine power and poor acceleration
- Increased fuel consumption
- Engine misfires or hesitation during acceleration
- Check engine light illumination

Diagnosis:
- Inspect ignition components such as spark plugs, ignition coils, and wires for wear or damage
- Check for vacuum leaks around intake manifold and hoses
- Test fuel injectors for proper spray pattern and operation
- Scan engine control unit (ECU) for fault codes related to sensors like oxygen sensor or throttle position sensor
- Examine timing belt condition and tension as wear can cause timing issues
- Verify proper operation of the idle control valve and throttle body cleanliness

Fixes:
- Replace worn or fouled spark plugs and faulty ignition components
- Repair or replace cracked or leaking vacuum hoses
- Clean or replace clogged fuel injectors
- Replace faulty sensors triggering error codes
- Change timing belt if worn or beyond recommended service interval to prevent engine damage
- Clean throttle body and idle control valve to restore smooth idling
- Perform a full tune-up including air and fuel filters replacement

Prevention:
- Follow manufacturer’s recommended maintenance schedule for timing belt replacement and tune-ups
- Use quality fuel and replace fuel filter regularly to prevent injector clogging
- Regularly inspect and replace ignition components as needed
- Keep intake system clean and free of leaks to maintain proper air-fuel mixture
- Address check engine light warnings promptly to avoid further damage
- Maintain proper engine oil levels and change oil at recommended intervals to ensure engine longevity
