2. Clean or Replace Throttle Body

• Tools Required: Throttle body cleaner, socket set, screwdriver.
• Remove the air intake duct to access the throttle body.
• Disconnect the throttle body connector and remove the mounting bolts.
• Clean the throttle body using throttle body cleaner and a soft cloth. Ensure the butterfly valve operates smoothly.

3. Check and Replace Fuel Filter (if necessary)

• Tools Required: Wrenches, catch pan.
• Locate the fuel filter (refer to the owner’s manual for location).
• Release the fuel pressure from the system.
• Disconnect the fuel lines and remove the old filter.

4. Inspect and Replace Mass Airflow Sensor (if faulty)

• Tools Required: Torx screwdriver.
• Locate the mass airflow sensor in the intake manifold.
• Unplug the electrical connector and remove the sensor.
• Inspect the sensor for dirt or damage. Clean it using appropriate MAF cleaner.
