Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure the engine is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Remove the throttle body from the intake manifold by loosening the mounting bolts (typically 10-15 ft-lbs torque). Use a socket wrench for this step.
Inspect the throttle body for carbon buildup and use throttle body cleaner and a soft cloth or brush to clean it thoroughly.
Ensure the throttle plate moves freely without obstruction.
Reinstall the throttle body and tighten the bolts to the specified torque.

3. Check Throttle Cable and Spring

Inspect the throttle cable for kinks or binding. If damaged, replace it with a new one.
Check the throttle return spring to ensure it is not broken or weakened. If necessary, replace the spring.

4. Test and Replace Throttle Position Sensor (if needed)

Using a multimeter, check the resistance of the TPS at various throttle positions. Compare the readings to the specifications in the service manual.
If the TPS is faulty, disconnect it and remove it from the throttle body.
Install a new throttle position sensor and reconnect the wiring harness.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle for a few minutes.
Test the throttle response by pressing the accelerator pedal and ensuring it operates smoothly.
