• Disconnect the battery to ensure safety during repairs.
• Remove any engine covers or components obstructing access to the throttle body and fuel system.

2. Clean Throttle Body

1. Remove the throttle body from the intake manifold.
   • Tools required: Socket set, torque wrench.
2. Use throttle body cleaner to clean the interior surfaces of the throttle body.
3. Reinstall the throttle body and torque to manufacturer specifications.

3. Inspect and Replace Accelerator Pedal Position Sensor (if necessary)

1. Disconnect the electrical connector from the accelerator pedal position sensor.
2. Remove the mounting screws and take out the sensor.
   • Tools required: Torx screwdriver.
3. Install the new sensor and reconnect the electrical connector.
4. Ensure proper alignment and secure all connections.

4. Fuel System Check

1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition key to the "On" position (do not start the engine) to check for initial fuel pressure.
3. If pressure is below specifications, replace the fuel filter and inspect the fuel pump for functionality.
   • Tools required: Fuel pressure gauge, socket set.

5. MAF Sensor Cleaning or Replacement

1. Locate the MAF sensor in the air intake duct.
