Solution

1. Preparation

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

2. Clean or Replace Throttle Body

• Remove the air intake duct to access the throttle body.
• Use a throttle body cleaner and a soft brush to remove carbon buildup.
• Reinstall the intake duct securely.

3. Replace Fuel Filter (if applicable)

• Locate the fuel filter; refer to the vehicle's manual for the exact location.
• Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
• Disconnect the fuel lines from the filter using a line wrench.
• Install the new fuel filter, ensuring proper orientation and secure connections.

4. Check and Replace Mass Air Flow (MAF) Sensor (if faulty)

• If faulty, replace with a new sensor.
• Reinstall the sensor and reconnect the electrical connector.

5. Transmission Fluid Check and Change (if needed)

• Remove the transmission dipstick and check fluid level; add fluid if low.
• If fluid is dark or burnt, consider a transmission fluid change; drain and refill with the manufacturer-recommended fluid.

Tools Required:

• OBD-II scanner
• Fuel pressure gauge
• Throttle body cleaner
• Line wrench
• Multimeter
• Socket set

Parts Required:

• Air filter
