Solution
1. Preparation
  • Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Using throttle body cleaner and a soft cloth, clean the inside of the throttle body, ensuring to remove any carbon deposits.
  • Reattach the air intake duct securely.
3. Replace the Air Filter
  • Open the air filter housing and remove the old air filter.
  • Install a new air filter according to the manufacturer's specifications, ensuring it is seated properly.
4. Check and Adjust Fuel Pressure
  • Connect a fuel pressure gauge to the fuel rail.
  • Start the engine and check that the fuel pressure is within the manufacturer's specified range. If it is low, replace the fuel pump or filter as necessary.
5. Inspect and Replace Vacuum Hoses
  • Visually inspect all vacuum hoses connected to the intake manifold for cracks or damage.
  • Replace any defective hoses with new ones, ensuring a snug fit.
6. Test Accelerator Pedal Position Sensor
  • Locate the accelerator pedal position sensor and disconnect the electrical connector.
  • Using a multimeter, measure the resistance or voltage output according to the specifications found in the service manual.
  • Replace the sensor if it is out of range.
