Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Fuel System

Remove the fuel pump fuse and crank the engine to relieve fuel pressure.
Disconnect the fuel line and inspect for leaks or blockages.
If necessary, replace the fuel filter and fuel pump.
Reconnect the fuel line and replace the fuel pump fuse.

3. Clean Throttle Body

Remove the air intake duct from the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and bore.
Reattach the air intake duct securely.

4. Replace Spark Plugs and Ignition Coils

Remove the engine cover (if applicable) to access the spark plugs.
Use a socket set to remove the old spark plugs.
Inspect the ignition coils and replace them if they show signs of wear.
Install new spark plugs, tightening them to the manufacturer's specified torque (typically 15-20 Nm).

5. MAF Sensor Inspection

Disconnect the MAF sensor connector.
Remove the sensor and inspect for dirt build-up.
Clean the MAF sensor with MAF cleaner (do not use other cleaners).
Reinstall the sensor and reconnect its electrical connector.
