Solution

1. Preparation

Tools Required:
- Throttle body cleaner
- Soft cloth or rags
- Screwdriver set
- Socket set
- Torque wrench
Disconnect the battery by removing the negative terminal to prevent electrical shorts.
Allow the engine to cool down completely before starting work.

2. Remove Air Intake Duct

Use a screwdriver or socket set to loosen the clamps on the air intake duct connecting to the throttle body.
Carefully detach the duct and set it aside, taking care not to damage any connecting hoses.

3. Access Throttle Body

Disconnect the electrical connector from the throttle position sensor (TPS) on the throttle body.
If applicable, remove any additional sensors or components blocking access to the throttle body.
Use a socket set to remove the bolts securing the throttle body to the intake manifold.

4. Clean the Throttle Body

Spray throttle body cleaner into the throttle body opening while opening the throttle plate manually with your fingers or a non-abrasive tool.
Wipe the inside of the throttle body with a soft cloth or rag, ensuring all carbon deposits and dirt are removed.
Pay special attention to the edges of the throttle plate and the intake manifold side.

5. Reassemble Components

Reattach the throttle body to the intake manifold, ensuring all bolts are tightened to the manufacturer’s specified torque (refer to the service manual for the exact torque value).
Reconnect any sensors or components removed earlier.
Reattach the air intake duct and secure it with clamps.

6. Final Steps

Reconnect the negative terminal of the battery.
Start the engine and allow it to idle for a few minutes to ensure proper throttle operation.
If the check engine light was on, use the OBD-II scanner to clear any error codes.
