Engine M112.916

Symptoms:
- Rough idling and misfires
- Loss of power or hesitation during acceleration
- Engine warning light (Check Engine) illumination
- Oil leaks around valve covers or camshaft seals
- Excessive oil consumption

Diagnosis:
- Inspect ignition coils and spark plugs for wear or damage, as misfires are common with aging ignition components.
- Perform a compression test to check for cylinder sealing issues.
- Check for vacuum leaks around intake manifold gaskets and hoses.
- Examine valve cover gaskets and camshaft seals for oil leaks.
- Scan the engine control unit (ECU) for fault codes related to ignition, fuel delivery, or sensor malfunctions.

Fixes:
- Replace worn spark plugs and faulty ignition coils to resolve misfires and rough running.
- Replace valve cover gaskets and camshaft seals to stop oil leaks.
- Repair or replace damaged vacuum hoses or intake manifold gaskets to eliminate vacuum leaks.
- Clean or replace the mass airflow sensor (MAF) and throttle body if dirty or malfunctioning.
- Address any detected sensor faults by replacing faulty sensors (e.g., oxygen sensors, crankshaft position sensor).
- Regular oil changes with the recommended grade to maintain engine lubrication and prevent sludge buildup.

Prevention:
- Follow the manufacturer’s recommended maintenance schedule, including timely spark plug and ignition coil replacement.
- Use high-quality engine oil and change it regularly to prevent sludge and wear.
- Inspect and replace aging gaskets and seals proactively to avoid leaks.
- Keep the air intake system clean to ensure proper airflow and sensor operation.
- Address engine warning lights promptly to prevent further damage.
