Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, socket set, screwdriver set, cleaning supplies, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Clean the Air Filter

Open the hood and locate the air intake box.
Remove the air intake duct using a screwdriver or socket set.
Take out the air filter and inspect it for dirt and clogs.
If dirty, replace the air filter with a new one.

3. Clean the Throttle Body

Remove the throttle body air intake duct.
Using throttle body cleaner, spray the inside of the throttle body while opening the throttle plate manually.
Wipe any carbon buildup with a clean cloth.
Reinstall the throttle body duct securely.

4. Check and Clean the MAF Sensor

Locate the MAF sensor in the air intake system.
Disconnect the wiring harness carefully.
Remove the sensor using the appropriate socket.
Clean the sensor with MAF cleaner, allowing it to dry completely before reinstalling.

5. Verify Fuel System Components

Check the fuel filter for clogs; replace if necessary.
Listen for the fuel pump operation when the ignition is turned on (without starting).
If the pump is faulty, replace it according to manufacturer specifications.
