1. Preparation

Tools Required:
- Socket set
- Screwdrivers (flathead and Phillips)
- Throttle body cleaner
- Soft cloth or paper towels
- Safety gloves
Safety Warnings: Disconnect the battery before working on electrical components. Allow the engine to cool before starting.

2. Remove Engine Cover (if applicable)

Use a socket set or screwdriver to remove any screws or bolts securing the engine cover.
Lift the cover off and set it aside in a safe location.

3. Access the Throttle Body

Disconnect the air intake duct by loosening the hose clamps and carefully pulling it off.

Remove any additional components obstructing access to the throttle body, such as sensors or brackets.

4. Clean the Throttle Body

Spray throttle body cleaner directly onto a soft cloth or paper towel.
Wipe the inside of the throttle body, focusing on the throttle plate and surrounding areas. Ensure you do not allow any cleaner to enter the intake manifold.
For heavy deposits, spray the cleaner directly into the throttle body and allow it to soak for a few minutes before wiping again.
Ensure the throttle plate moves freely and does not have any residue left.

5. Reassemble Components

Reattach any components removed earlier, ensuring that electrical connectors are securely fastened.
Reconnect the air intake duct and tighten the hose clamps.
Replace the engine cover if it was removed.

6. Final Checks

Reconnect the battery.
Start the engine and allow it to idle for a few minutes to ensure proper operation.
