Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Throttle Body

Sub-steps:
1. Locate the throttle body on the intake manifold.
2. Remove the air intake duct connected to the throttle body by loosening the clamps and disconnecting any sensors.
3. Disconnect the throttle body electrical connector by pressing the release tab and gently pulling it off.
4. Remove the four mounting bolts securing the throttle body using a socket set (typically 8mm or 10mm).
5. Carefully remove the throttle body from the intake manifold, taking care not to damage the gasket.

3. Inspect and Clean Throttle Body

Sub-steps:
1. Inspect the throttle plate and bore for carbon buildup or dirt.
2. Use throttle body cleaner and a clean cloth to gently clean the throttle plate and surrounding areas.
3. Ensure the throttle plate moves freely and does not have any obstructions.
4. Check the gasket for damage; replace if necessary.

4. Reinstall Throttle Body

Sub-steps:
1. Position the cleaned throttle body on the intake manifold, ensuring proper alignment with the gasket.
2. Reinstall the four mounting bolts and torque them to the manufacturer's specifications (usually around 89-108 inch-pounds).
3. Reconnect the throttle body electrical connector until it clicks securely.
4. Reattach the air intake duct and tighten all clamps.

5. Final Steps

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the engine and allow it to idle, checking for any irregularities.
3. Test drive the vehicle to ensure proper throttle response.
