Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, clean rags
Remove the air intake hose connected to the throttle body.
Spray throttle body cleaner inside the throttle body while opening the throttle plate manually.
Use a soft brush to remove carbon deposits, then wipe clean with a rag.
Reattach the air intake hose securely.

3. Replace Throttle Position Sensor (if faulty)

Tools Required: Socket set, torque wrench
Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the screws holding the sensor.
Install the new throttle position sensor and secure it with screws. Torque to manufacturer's specifications.
Reconnect the electrical connector.

4. Inspect and Replace Fuel Filter (if necessary)

Tools Required: Wrench set, fuel line disconnect tool
Locate the fuel filter in the fuel line. Depressurize the fuel system by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a fuel line disconnect tool.
Remove the old fuel filter and install the new one, ensuring proper orientation.
Reconnect the fuel lines and reinstall the fuel pump fuse.
