Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electronic components.
2. Clean Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body.
  • Ensure the throttle plate moves freely; reassemble the air intake duct.
3. Inspect Transmission Fluid
  • With the vehicle on a level surface, remove the transmission dipstick and check the fluid level.
  • If low, add the manufacturer-recommended transmission fluid.
  • If fluid appears dark or has a burnt smell, consider a transmission fluid change.
4. Verify Fuel Pressure
  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position (do not start) and check the pressure reading against manufacturer specifications.
  • If pressure is low, inspect the fuel pump and fuel filter for blockages.
5. Replace Spark Plugs and Ignition Coils (if necessary)
  • Remove the ignition coil cover to access the spark plugs.
  • Use a spark plug socket to remove old spark plugs and replace them with new ones, ensuring the correct gap.
  • Reinstall ignition coils and secure the cover.
