Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdrivers, cleaning solvent, rags
Disconnect the negative battery cable to ensure safety while working on electrical components.
Wear safety goggles and gloves.

2. Remove Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body by loosening the clamps and disconnecting any sensors.
2. Unbolt the throttle body from the intake manifold using the socket set (usually 10mm bolts).
3. Carefully detach the electrical connector from the throttle body.

3. Inspect and Clean

Sub-steps:
1. Examine the throttle body for carbon buildup or debris that could cause it to stick.
2. Use a suitable cleaning solvent and a clean rag to wipe down the throttle plate and surrounding areas.
3. Check the throttle plate's movement for smooth operation; it should open and close freely.

4. Reinstall Throttle Body

Sub-steps:
1. Reconnect the electrical connector to the throttle body.
2. Align and bolt the throttle body back onto the intake manifold, ensuring it's seated properly.
3. Reattach the air intake duct and secure it with clamps.

5. Reset and Test

Sub-steps:
1. Reconnect the negative battery cable.
2. Start the engine and allow it to idle, checking for any unusual behavior.
3. Use the OBD-II scanner to clear any stored error codes and monitor for any reoccurrences.
