Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on the vehicle.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Inspect the air filter; if dirty, clean or replace it with a new OEM filter.
Reassemble the air filter housing cover securely.

3. Clean Throttle Body

Remove the intake duct connecting to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body, ensuring the butterfly valve operates smoothly.
Reattach the intake duct and ensure all connections are secure.

4. Replace Spark Plugs

Remove the ignition coil cover (if applicable) using a socket set.
Disconnect ignition coils and remove them from the spark plug holes.
Use a spark plug socket to remove the old spark plugs and replace them with new ones, tightening to the manufacturer's torque specifications (typically around 13-15 ft-lbs).
Reinstall the ignition coils and cover.

5. Check and Clean MAF Sensor

Locate the MAF sensor in the intake duct.
Disconnect the electrical connector and remove the sensor.
Use MAF cleaner to carefully clean the sensor element, avoiding physical contact.
Reinstall the MAF sensor and reconnect the electrical connector.
