Engine BBM

Symptoms:
- Rough idling and occasional stalling
- Loss of power and reduced fuel efficiency
- Engine misfires or hesitation during acceleration
- Check Engine Light (CEL) illumination

Diagnosis:
- Inspect ignition coils and spark plugs for wear or damage, as these are common failure points causing misfires.
- Check the fuel injectors for clogging or leaks, which can lead to poor fuel delivery.
- Perform a compression test to rule out internal engine wear or valve issues.
- Scan the engine control unit (ECU) for fault codes related to sensors such as the oxygen sensor or mass airflow sensor.
- Examine the timing belt condition and tension, as improper timing can cause performance issues.

Fixes:
- Replace worn or faulty spark plugs and ignition coils to restore proper combustion.
- Clean or replace clogged fuel injectors to ensure correct fuel atomization.
- Repair or replace faulty sensors identified by diagnostic trouble codes.
- Replace the timing belt if it shows signs of wear or has exceeded the recommended service interval to prevent engine damage.
- Address any vacuum leaks by inspecting hoses and intake manifold gaskets.

Prevention:
- Follow the manufacturer’s recommended maintenance schedule, including timely replacement of spark plugs, ignition components, and timing belt.
- Use high-quality fuel and perform regular fuel system cleaning to prevent injector clogging.
- Regularly check and replace air filters to maintain proper air intake.
- Monitor engine performance and address any warning signs promptly to avoid escalation.
- Keep the engine oil and coolant at proper levels and change them as per service intervals to ensure optimal engine health.
