Engine M137.970

Symptoms:
- Rough idling and misfires
- Loss of power and poor acceleration
- Excessive oil consumption and smoke from exhaust
- Engine overheating or coolant leaks
- Check engine light illumination

Diagnosis:
- Inspect ignition system components (spark plugs, coils) for wear or failure causing misfires.
- Check for vacuum leaks or intake manifold gasket failure leading to rough running.
- Perform compression test to detect worn piston rings or cylinder walls causing oil consumption.
- Examine cooling system for leaks, thermostat function, and radiator condition to address overheating.
- Scan engine control unit (ECU) for fault codes related to sensors or fuel injection issues.

Fixes:
- Replace worn spark plugs and ignition coils to restore proper combustion.
- Repair or replace intake manifold gaskets and vacuum hoses to eliminate leaks.
- Overhaul engine components such as piston rings or valve stem seals if oil consumption is excessive.
- Flush and repair cooling system parts including radiator, water pump, and thermostat as needed.
- Update or repair ECU sensors and fuel injectors to ensure correct engine management.

Prevention:
- Regularly service ignition components and replace spark plugs at recommended intervals.
- Maintain cooling system with periodic coolant changes and inspections for leaks.
- Use high-quality engine oil and change it according to manufacturer guidelines to reduce wear.
- Avoid prolonged idling and aggressive driving to minimize engine stress.
- Conduct routine diagnostic scans to catch early signs of sensor or system malfunctions.
