Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical issues.
2. Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a clean rag to remove carbon buildup from the throttle plate and body.
  • Ensure the throttle plate moves freely and is not stuck.
3. Inspect and Replace the Throttle Position Sensor (if needed)
  • Disconnect the electrical connector from the TPS.
  • Remove the mounting screws and take out the TPS.
  • Install the new TPS and torque the screws to the manufacturer's specifications (usually around 7-10 ft-lbs).
  • Reconnect the electrical connector.
4. Check and Replace the Accelerator Pedal Position Sensor (if needed)
  • Disconnect the battery again for safety.
  • Remove any panels obstructing access to the accelerator pedal assembly.
  • Disconnect the electrical connector from the APPS.
  • Remove the sensor from the pedal assembly.
  • Install the new APPS and ensure it is aligned properly.
  • Reconnect the electrical connector and any panels removed.
5. Reconnect Battery and Test Drive
  • Reconnect the negative battery terminal.
  • Start the engine and let it idle for a few minutes.
  • Take the vehicle for a test drive to check for improvement in throttle response.
