Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, throttle body cleaner, and a soft cloth.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts and ensure safety.

2. Inspect and Clean the Throttle Body

Remove the Throttle Body:
- Disconnect the electrical connectors from the throttle body.
- Remove the intake air duct connected to the throttle body using a socket set.
- Unbolt the throttle body from the intake manifold (typically 2-4 bolts).
Clean the Throttle Body:
- Use throttle body cleaner and a soft cloth to remove carbon buildup and debris from the throttle plate and body.
- Ensure the throttle plate moves freely without binding.
Reinstall the Throttle Body:
- Position the throttle body back onto the intake manifold and secure with bolts.
- Reconnect the intake air duct and electrical connectors.

3. Inspect and Replace the Throttle Cable (if applicable)

Check the Throttle Cable:
- Inspect for fraying, binding, or excessive slack.
- If damaged, note the routing for installation of the new cable.
Replace the Throttle Cable:
- Disconnect the old cable from the throttle body and pedal assembly.
- Route the new cable in the same manner as the old one, securing it in place.
- Connect the new cable to the throttle body and pedal assembly.

4. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle.
Test the throttle response by gently pressing the accelerator pedal.
