Solution

1. Preparation

Gather required tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is in a well-ventilated area.

2. Clean Throttle Body

Tools Required: Throttle body cleaner, microfiber cloth, socket set.
Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner onto a microfiber cloth and wipe the internal surfaces of the throttle body to remove carbon deposits.
Ensure the throttle plate can move freely and is not obstructed by debris.

3. Inspect and Replace Throttle Position Sensor (if necessary)

Tools Required: Multimeter, socket set.
Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the TPS.
Use a multimeter to test the sensor's resistance and voltage output according to manufacturer specifications.
If the sensor is faulty, remove the screws holding it in place and replace it with a new unit. Reconnect the electrical connector.

4. Reassemble Components

Reattach the air intake duct securely to the throttle body.
Reconnect the battery terminal.
Ensure all connections are tight and no tools are left in the engine bay.
