Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery for safety.
  • Ensure the vehicle is on a level surface and use wheel chocks.
2. Replace Air Filter
  • Remove the air filter cover using a socket set.
  • Take out the old air filter and inspect the housing for debris.
  • Install the new air filter in the correct orientation.
  • Reattach the air filter cover and secure it.
3. Clean Fuel Injectors
  • If injectors are accessible, remove them from the intake manifold using the appropriate size socket.
  • Use an injector cleaning kit or ultrasonic cleaner to clean the injectors.
  • Reinstall the cleaned injectors, ensuring O-rings are replaced to prevent leaks.
4. Inspect and Replace Spark Plugs
  • Remove the ignition coil cover if applicable.
  • Use a spark plug socket to remove each spark plug.
  • Inspect the spark plugs for wear; replace them if necessary with OEM parts.
  • Reinstall the spark plugs and ignition coils, ensuring they are properly seated.
5. Check Tire Pressure
  • Use a tire pressure gauge to check each tire's pressure.
  • Inflate tires to the manufacturer's recommended PSI if low.
  • Inspect tire tread and consider replacement if excessive wear is present.
