Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Clean or Replace the Air Filter

Remove the air intake duct by loosening the clamps with a socket set.
Take out the air filter and inspect it for dirt and damage.
If dirty, clean it with compressed air or replace it with a new one.
Reinstall the air intake duct securely.

3. Inspect and Clean the Throttle Body

Disconnect the negative battery terminal to prevent electrical shorts.
Remove the throttle body housing using the socket set.
Use throttle body cleaner and a soft cloth to remove carbon deposits.
Reassemble the throttle body and reconnect the battery terminal.

4. Check and Replace Spark Plugs and Ignition Coils

Remove the engine cover if applicable to access the ignition components.
Unscrew and remove the spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace if necessary with OEM-recommended plugs.
Check ignition coils for damage and replace any faulty coils.
Reinstall the spark plugs and engine cover.

5. Test and Replace the MAF Sensor (if necessary)

Disconnect the MAF sensor electrical connector.
Use a multimeter to test the MAF sensor according to manufacturer specifications.
If faulty, replace the MAF sensor with a new one.
Reconnect the electrical connector and ensure the sensor is securely in place.
