Vehicles using AWG engine list:

Engine AWG

Symptoms:
- Rough idling and occasional stalling
- Loss of power and reduced fuel efficiency
- Engine misfires or hesitation during acceleration
- Check Engine Light (CEL) illumination

Diagnosis:
- Inspect ignition coils and spark plugs for wear or damage, as AWG engines are prone to ignition issues.
- Perform a compression test to check for cylinder sealing problems.
- Check for vacuum leaks around intake manifold gaskets and hoses.
- Scan the engine control unit (ECU) for fault codes related to misfires, oxygen sensors, or fuel trim.
- Examine the camshaft position sensor and crankshaft position sensor for proper operation.

Fixes:
- Replace worn or faulty spark plugs and ignition coils to restore proper combustion.
- Repair or replace leaking intake manifold gaskets to eliminate vacuum leaks.
- Clean or replace the mass airflow sensor (MAF) if dirty or malfunctioning.
- Address any ECU fault codes by replacing faulty sensors such as oxygen sensors or camshaft/crankshaft sensors.
- If compression test reveals issues, investigate potential head gasket leaks or valve problems and repair accordingly.

Prevention:
- Follow regular maintenance schedules, including timely spark plug and ignition coil replacement.
- Use quality fuel and keep the fuel system clean to prevent injector clogging.
- Regularly inspect and replace air filters to ensure proper airflow.
- Avoid prolonged idling and aggressive driving to reduce engine stress.
- Periodically check for vacuum leaks and sensor functionality to catch issues early.
