Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Clean Throttle Body

Tools Required: Socket set, throttle body cleaner, rags.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a rag to clean the inside of the throttle body to remove any carbon buildup.
Ensure that the throttle plate can move freely after cleaning.

3. Check Throttle Cable and Linkage

Tools Required: Screwdrivers, socket set.
Inspect the throttle cable for any signs of wear or binding.
Adjust or replace the throttle cable if necessary.
Check the linkage for proper movement; lubricate if it appears stiff.

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

Tools Required: Multimeter, socket set.
Disconnect the throttle position sensor connector.
Use a multimeter to measure the voltage output of the TPS while moving the throttle. It should change smoothly.
If the readings are erratic or out of spec, replace the TPS with a new part.

5. Reassemble and Reconnect

Reinstall the cleaned throttle body and air intake duct.
Reconnect the negative battery terminal.
Clear any diagnostic trouble codes using the OBD-II scanner.
