Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the air filter cover.
Take out the old air filter and inspect it for dirt and damage.
Install a new air filter (OEM recommended) and reattach the cover.

3. Check and Replace Spark Plugs

Remove the ignition coil cover if applicable.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils using a socket set.
Use a spark plug socket to remove old spark plugs.
Inspect the old plugs; replace with new plugs (ensure correct gap settings).
Reinstall ignition coils and reconnect electrical connectors.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body interior.
Ensure the throttle plate opens and closes freely.
Reattach the intake duct securely.

5. Test and Replace MAF Sensor (if necessary)

Locate the MAF sensor in the intake system.
Disconnect the electrical connector and remove the sensor.
Clean the MAF sensor with MAF cleaner.
If issues persist, replace the MAF sensor with a new one.
