Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, throttle body cleaner, clean rags.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before beginning work.

2. Clean Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Disconnect the throttle position sensor connector.
Use throttle body cleaner and a clean rag to remove carbon deposits and dirt from the throttle body.
Ensure the throttle plate moves freely and is not sticking.
Reconnect the throttle position sensor and air intake duct.

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

Remove the screws securing the accelerator pedal assembly.
Disconnect the electrical connector from the accelerator pedal position sensor.
Install a new sensor if faulty, ensuring it is aligned correctly.
Re-secure the accelerator pedal assembly.

4. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter along the fuel line.
Depressurize the fuel system by removing the fuel pump relay.
Disconnect the fuel lines from the filter using appropriate tools.
Install the new fuel filter, ensuring proper orientation.
Reconnect the fuel pump relay and prime the fuel system before starting the engine.
