Solution
1. Preparation
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety during electrical work.
2. Inspect and Clean Throttle Body
  • Remove the air intake duct connected to the throttle body using a socket set.
  • Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon deposits.
  • Reattach the air intake duct securely.
3. Check and Clean MAF Sensor
  • Disconnect the MAF sensor connector and remove the sensor from the air intake.
  • Clean the MAF sensor using MAF sensor cleaner (do not touch the sensing elements).
  • Reinstall the MAF sensor, ensuring a secure connection.
4. Test Throttle Position Sensor (TPS)
  • Locate the TPS on the throttle body and disconnect the electrical connector.
  • Using a multimeter, measure the resistance or voltage output while moving the throttle plate gently.
  • Replace the TPS if readings are outside the manufacturer’s specifications.
5. Inspect Transmission Fluid
  • Remove the transmission dipstick (if equipped) and check the fluid level and condition.
  • If the fluid is low or burnt, replace it with the manufacturer-recommended transmission fluid.
  • Recheck the transmission operation after fluid replacement.
