Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Disconnect the battery to prevent electrical shorts.
  • Allow the engine to cool before starting work.
2. Clean the Throttle Body
  • Remove the intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft brush to clean the throttle plate and bore.
  • Reattach the intake duct securely.
3. Inspect and Test the Accelerator Pedal Position Sensor
  • Locate the accelerator pedal position sensor.
  • Disconnect the sensor connector and test the voltage output with a multimeter while pressing the accelerator.
  • If the voltage does not change smoothly from idle to full throttle, replace the sensor.
4. Check Fuel Delivery System
  • Inspect the fuel pump for proper operation by listening for the pump's sound when the ignition is turned on.
  • Replace the fuel filter if it is clogged or hasn’t been changed according to the maintenance schedule.
  • Ensure the fuel lines are free of leaks or kinks.
5. Reconnect Battery and Final Checks
  • Reconnect the battery terminals securely.
  • Start the engine and allow it to idle for a few minutes to stabilize.
