Vehicles using B200E engine list:

Engine B200E

Symptoms:
- Rough idling and poor acceleration
- Engine misfires or hesitation under load
- Hard starting, especially in cold conditions
- Increased fuel consumption
- Occasional stalling or uneven running

Diagnosis:
- Check ignition components: spark plugs, ignition coil, distributor cap, and rotor for wear or damage
- Inspect fuel delivery system including fuel filter and injectors for clogging or leaks
- Verify timing belt condition and timing marks alignment; worn or slipped belts cause timing issues
- Test sensors such as the coolant temperature sensor and throttle position sensor for proper operation
- Look for vacuum leaks in hoses and intake manifold gaskets that can cause lean running conditions
- Perform compression test to rule out internal engine wear or valve issues

Fixes:
- Replace worn spark plugs, ignition wires, distributor cap, and rotor to restore proper spark
- Change fuel filter regularly and clean or replace injectors as needed to ensure fuel flow
- Replace timing belt at recommended intervals (usually every 60,000 to 90,000 km) to prevent failure and maintain timing
- Repair or replace faulty sensors to improve engine management and drivability
- Fix vacuum leaks by replacing cracked hoses or gaskets
- Address any internal engine problems found during compression testing, such as valve adjustments or gasket replacement

Prevention:
- Follow manufacturer’s maintenance schedule strictly, especially for timing belt and ignition system components
- Use quality fuel and replace fuel filter regularly to avoid injector clogging
- Regularly inspect vacuum lines and intake components for cracks or leaks
- Keep cooling system in good condition to prevent overheating and sensor failures
- Perform periodic tune-ups including spark plug replacement and ignition system checks to maintain engine performance and longevity
