Engine B4184S11

Symptoms:
- Rough idling and occasional stalling
- Loss of power or hesitation during acceleration
- Increased oil consumption or minor oil leaks
- Check Engine Light (CEL) illumination, often related to misfires or sensor faults
- Unusual engine noises, such as ticking or knocking

Diagnosis:
- Inspect ignition coils and spark plugs for wear or failure, common causes of misfires
- Check for vacuum leaks around intake manifold and hoses, which can cause rough idling
- Perform a compression test to rule out internal engine wear or valve issues
- Scan the ECU for fault codes related to oxygen sensors, MAF sensor, or camshaft position sensor
- Examine PCV valve and associated hoses for clogging or damage, contributing to oil leaks and rough running

Fixes:
- Replace worn spark plugs and faulty ignition coils to restore smooth combustion
- Repair or replace damaged vacuum hoses and intake manifold gaskets to eliminate leaks
- Clean or replace MAF and oxygen sensors if faulty readings are detected
- Service or replace the PCV valve to prevent oil leaks and maintain proper crankcase ventilation
- Address oil leaks by replacing valve cover gaskets or camshaft seals as needed
- If compression test reveals issues, consider valve adjustment or more extensive engine repairs

Prevention:
- Follow regular maintenance schedule including timely spark plug and ignition coil replacement
- Use high-quality engine oil and change it at recommended intervals to reduce wear and oil consumption
- Periodically inspect and clean air intake components and sensors to ensure accurate readings
- Monitor for early signs of vacuum leaks or oil leaks and address promptly
- Avoid prolonged idling and aggressive driving to reduce engine stress and prolong component life
