Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface, and engage the parking brake.
  • Disconnect the battery to prevent any electrical shorts.
2. Inspect the Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
  • Reinstall the air intake duct securely.
3. Check the Accelerator Pedal Position Sensor
  • Locate the accelerator pedal assembly and disconnect the electrical connector.
  • Use a multimeter to test the sensor output while slowly pressing the accelerator pedal.
    • Expected output should increase smoothly from 0.5V to 4.5V.
  • If the readings are inconsistent, replace the sensor.
4. Transmission Fluid Inspection
  • Locate the transmission dipstick and check fluid level; add fluid if low.
  • Inspect fluid color and smell — it should be bright red and not burnt.
  • If fluid is discolored, consider a transmission fluid change.
5. Verify Mass Air Flow (MAF) Sensor
  • Disconnect the MAF sensor electrical connector.
  • Clean the MAF sensor using MAF cleaner and allow it to dry.
  • Reconnect the sensor and test drive the vehicle to determine if the issue persists.
