Symptoms:
- Rough idling and hesitation during acceleration
- Hard starting, especially in cold weather
- Decreased fuel efficiency and power loss
- Engine misfires or backfires
- Excessive oil consumption or smoke from the exhaust

Diagnosis:
- Check ignition components: distributor cap, rotor, spark plugs, and wires for wear or corrosion
- Inspect the fuel system, including fuel filter and injectors, for clogs or leaks
- Test the idle air control valve and throttle body for proper operation and cleanliness
- Examine vacuum lines for cracks or disconnections causing air leaks
- Perform a compression test to assess cylinder health and head gasket integrity
- Check timing belt condition and alignment to ensure correct valve timing

Fixes:
- Replace worn or faulty ignition parts such as spark plugs, wires, distributor cap, and rotor
- Clean or replace fuel injectors and fuel filter to restore proper fuel delivery
- Clean throttle body and idle air control valve to stabilize idle speed
- Repair or replace damaged vacuum hoses to eliminate air leaks
- Replace timing belt if worn or misaligned to prevent engine damage
- Address oil leaks by replacing gaskets and seals as needed
- Perform valve adjustments if compression test indicates valve issues

Prevention:
- Follow regular maintenance schedule including timely replacement of spark plugs, ignition components, and fuel filters
- Use quality fuel and oil to reduce deposits and wear
- Inspect and replace timing belt every 60,000 to 100,000 km to avoid catastrophic failure
- Keep the cooling system in good condition to prevent overheating and gasket failure
- Regularly check for vacuum leaks and repair promptly to maintain engine performance
- Maintain clean air intake and throttle body to ensure smooth engine operation
