Solution

1. Preparation

Gather tools and materials: throttle body cleaner, soft cloths, a socket set, and a screwdriver.
Disconnect the negative terminal of the battery to avoid electrical issues during cleaning.
Allow the engine to cool completely before starting work.

2. Remove the Throttle Body

Locate the throttle body, usually found between the air intake and the intake manifold.
Disconnect the electrical connector from the throttle body.
Remove the air intake duct connected to the throttle body by loosening the clamps with a screwdriver.
Unbolt the throttle body using the socket set (typically 10mm bolts) and carefully remove it from the intake manifold.

3. Clean the Throttle Body

Spray throttle body cleaner onto a soft cloth or directly onto the inside of the throttle body.
Gently wipe the throttle plate and surrounding areas, ensuring not to damage any components.
Pay attention to the edges and the intake manifold side where carbon deposits are likely to accumulate.
Use a soft brush if necessary to remove stubborn deposits, ensuring no bristles are left behind.

4. Reinstall the Throttle Body

Position the cleaned throttle body back onto the intake manifold.
Secure it with the bolts, tightening them to the manufacturer’s specified torque (typically around 15-20 ft-lbs).
Reattach the air intake duct and tighten the clamps.
Reconnect the electrical connector to the throttle body.

5. Final Steps

Reconnect the negative terminal of the battery.
Start the engine and allow it to idle, checking for smooth operation.
If necessary, perform an idle relearn procedure according to manufacturer specifications.
