Solution

1. Preparation

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

2. Inspect and Clean Throttle Body

Remove the air intake hose connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plates and surrounding areas.
Ensure no debris or carbon build-up is obstructing the throttle plate movement.

3. Check and Adjust Throttle Cable

Locate the throttle cable at the throttle pedal assembly.
Disconnect the throttle cable from the throttle body.
Inspect for fraying or binding; replace if damaged.
Adjust the cable tension by ensuring there is a small amount of slack in the cable when the pedal is at rest.

4. Replace Throttle Position Sensor (if necessary)

Disconnect the electrical connector from the TPS.
Remove the TPS by unscrewing the mounting screws.
Install the new TPS, ensuring it is properly aligned and secured.
Reconnect the electrical connector.

5. Reassemble and Test

Reattach the air intake hose to the throttle body.
Reconnect the battery.
Start the engine and allow it to idle.
Test the throttle response by pressing the pedal and ensuring smooth operation.
