Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down if it has been running.

2. Remove Throttle Body

Tools Required: Socket set, torque wrench, screwdriver set.
Remove the air intake duct connected to the throttle body by loosening the clamps and detaching the duct.
Disconnect the electrical connector from the throttle body.
Remove the throttle body mounting bolts using a socket and ratchet.
Carefully lift the throttle body off the intake manifold.

3. Clean Throttle Body

Inspect the throttle plate for carbon buildup or debris.
Use throttle body cleaner and a soft cloth or brush to clean the throttle plate and the inside of the throttle body.
Ensure the throttle plate opens and closes freely after cleaning.

4. Reinstall Throttle Body

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

5. Reconnect Battery and Reset System

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes to let the throttle body relearn its position.
