Engine B200G

Symptoms:
- Rough idling and hesitation during acceleration
- Reduced power and fuel efficiency
- Engine misfires or stalls intermittently
- Excessive oil consumption or minor leaks
- Difficulty starting, especially in cold weather

Diagnosis:
- Check ignition components: spark plugs, wires, distributor cap, and rotor for wear or corrosion
- Inspect fuel system: fuel filter clogging or weak fuel pump pressure
- Examine vacuum lines for leaks causing erratic idle
- Test compression to rule out worn piston rings or valves
- Verify timing belt condition and alignment; incorrect timing causes poor running
- Scan for any stored fault codes if equipped with diagnostic connectors

Fixes:
- Replace worn spark plugs and ignition parts to restore proper firing
- Change fuel filter regularly and ensure fuel pump delivers correct pressure
- Repair or replace cracked or disconnected vacuum hoses
- Adjust or replace timing belt as per maintenance schedule to maintain timing accuracy
- Address oil leaks by replacing gaskets or seals, especially valve cover gasket
- Clean or rebuild carburetor or fuel injection components if clogged or malfunctioning

Prevention:
- Follow recommended maintenance intervals for timing belt, spark plugs, and fuel filters
- Use quality fuel and oil to reduce deposits and wear
- Regularly inspect vacuum lines and ignition system for early signs of deterioration
- Avoid prolonged idling and harsh driving to minimize engine stress
- Keep engine oil at proper levels and change oil on schedule to protect internal components
