Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool if it was recently running.

2. Remove the Throttle Body

Tools Required: Socket set, torque wrench, flathead screwdriver
Loosen the clamps securing the air intake tubing to the throttle body.
Remove any electrical connectors from the throttle body.
Unscrew the throttle body mounting bolts using a socket set.
Carefully lift the throttle body from the intake manifold.

3. Inspect and Clean

Inspect the throttle body for carbon deposits and damage.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body thoroughly.
Check the throttle plate for free movement; if stuck, ensure there are no obstructions.
Inspect the TPS for damage. If faulty, replace it with a new sensor.

4. Reinstall the Throttle Body

Place the cleaned throttle body back onto the intake manifold.
Tighten the mounting bolts to the specified torque (typically 89 inch-lbs or as specified in the service manual).
Reconnect the electrical connectors and ensure they are secure.
Reattach the air intake tubing and tighten the clamps.

5. Finalize and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes to ensure proper operation.
Perform a throttle position reset if necessary by cycling the ignition on and off.
