Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shocks.
  • Allow the engine to cool if it has been running.
2. Clean Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
  • Reinstall the air intake duct and ensure all connections are secure.
3. Inspect and Test Accelerator Pedal Position Sensor
  • Locate the accelerator pedal position sensor (usually found on the pedal assembly).
  • Disconnect the electrical connector from the sensor.
  • Use a multimeter to check the resistance across the sensor terminals while pressing the accelerator pedal. Compare readings with manufacturer specifications.
  • If out of specifications, replace the sensor.
4. Check Transmission Fluid
  • Locate the transmission dipstick and remove it.
  • Wipe it clean and reinsert it to check the fluid level.
  • If low, add the recommended transmission fluid (consult the owner's manual for specifications).
  • If the fluid is dark or has a burnt smell, consider flushing the transmission.
5. Inspect for Vacuum Leaks
  • Visually inspect all hoses connected to the intake manifold for cracks or disconnections.
  • Use a smoke machine or carburetor cleaner around the intake area while the engine is running to detect leaks.
  • Replace any damaged hoses or gaskets.
