Solution
1. Preparation
  • Ensure the vehicle is parked on a flat 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 using a socket set.
  • Use throttle body cleaner and a soft cloth to clean the interior surfaces of the throttle body.
  • Reinstall the air intake duct and tighten the clamps securely.
3. Replace the Throttle Position Sensor (if faulty)
  • Locate the throttle position sensor on the throttle body.
  • Disconnect the electrical connector from the TPS.
  • Remove the TPS using a socket set and replace it with a new sensor.
  • Reconnect the electrical connector and ensure it is secure.
4. Clean or Replace the Mass Air Flow Sensor (if necessary)
  • Disconnect the electrical connector from the MAF sensor.
  • Remove the MAF sensor from the intake using a screwdriver.
  • If cleaning, use MAF cleaner to spray the sensor elements without touching them. If replacement, install a new MAF sensor.
  • Reconnect the electrical connector.
5. Inspect the Fuel System
  • Use a fuel pressure gauge to check the fuel pressure at the fuel rail.
  • Replace the fuel filter if clogged or replace the fuel pump if pressure is below specification.
