Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting any work.

2. Clean or Replace the Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it.
- If dirty or damaged, replace it with a new one.
Reinstall the housing cover and ensure it is secure.

3. Clean the Throttle Body

Locate the throttle body; remove the intake duct by loosening the clamps.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reattach the intake duct and secure it with the clamps.

4. Inspect and Replace Ignition Components

Remove the ignition coils by unscrewing them from the engine.
Check the spark plugs for wear; replace if they show signs of wear or damage.
Install new spark plugs and reattach the ignition coils, torquing to manufacturer specifications.

5. Test and Clean the MAF Sensor

Disconnect the MAF sensor connector and remove the sensor from its housing.
Clean the sensor using MAF cleaner, avoiding any physical contact with the sensor element.
Reinstall the MAF sensor and reconnect the connector.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any error codes that were recorded.
Start the engine and allow it to idle for a few minutes, monitoring for any irregularities.
