Symptoms:
- Rough idling and stalling during low RPMs
- Reduced engine power and poor acceleration
- Excessive fuel consumption
- Engine misfires or hesitation
- Difficulty starting the engine, especially when cold

Diagnosis:
- Check for vacuum leaks around intake manifold and hoses, as these can cause rough idling and stalling.
- Inspect spark plugs and ignition components for wear or fouling, which lead to misfires.
- Test the carburetor or fuel injection system for proper fuel delivery and adjustment.

- Repair or replace cracked or leaking vacuum hoses.
- Clean, rebuild, or adjust the carburetor to ensure correct fuel mixture.
- Replace the timing belt if worn and reset ignition timing to factory specifications.
- Change the air filter regularly to maintain airflow.
- Clean fuel injectors or replace fuel filters to improve fuel delivery.
- Address any electrical issues by repairing wiring or replacing faulty sensors.

Prevention:
- Perform regular maintenance including timely spark plug replacement and ignition system checks.
- Replace air and fuel filters according to the manufacturer’s schedule.
- Inspect and replace vacuum hoses periodically to prevent leaks.
- Change the timing belt at recommended intervals to avoid engine damage.
- Use quality fuel and keep the carburetor or fuel injection system clean.
