Solution

1. Preparation

Tools Required: Socket set, screwdrivers, cleaning brush, throttle body cleaner, rags, safety goggles, gloves.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the engine to cool before starting the cleaning process.

2. Remove the Throttle Body

Locate the throttle body assembly attached to the intake manifold.
Using a socket set, remove the bolts securing the throttle body.
Carefully disconnect the electrical connectors and any vacuum hoses attached to the throttle body.
Gently lift the throttle body off the intake manifold.

3. Clean the Throttle Body

Spray throttle body cleaner onto a clean rag or directly onto the throttle body surfaces.
Use a cleaning brush to scrub away carbon deposits and dirt, paying close attention to the throttle plate and bore.
Ensure that the cleaner does not enter the intake manifold excessively; avoid flooding.
Wipe down all surfaces with a clean rag to remove any residue from the cleaner.

4. Reinstall the Throttle Body

Position the throttle body back onto the intake manifold.
Reconnect the electrical connectors and vacuum hoses to their respective locations.
Secure the throttle body with the bolts, tightening them to the manufacturer's specified torque value (typically around 89 in-lbs, but confirm with service manual).
Reinstall the engine cover if applicable.

5. Final Checks

Reconnect the negative terminal of the battery.
Start the engine and allow it to idle for a few minutes, checking for any irregularities.
