Solution
1. Preparation
  • Gather tools and ensure the vehicle is parked on a level surface.
  • Disconnect the battery to avoid electrical shorts while working on components.
2. Air Filter Replacement
  • Remove the air filter housing cover using a socket set.
  • Take out the old air filter and inspect the housing for debris.
  • Install a new air filter ensuring it fits securely in the housing.
  • Reattach the housing cover and tighten the screws.
3. Throttle Body Cleaning
  • Remove the throttle body from the intake manifold by loosening the clamps and bolts (torque to manufacturer specifications when reassembling).
  • Use throttle body cleaner and a soft cloth to clean the interior surfaces.
  • Reinstall the throttle body, ensuring all connections are secure.
4. Fuel System Inspection
  • Attach a fuel pressure gauge to the fuel rail test port and turn the ignition to the ON position (do not start the engine).
  • Check the pressure reading against manufacturer specifications; replace the fuel pump if below spec.
  • If pressure is adequate, check the fuel filter for blockages and replace if necessary.
5. Ignition System Check
  • Remove the spark plugs using a spark plug socket; inspect for wear or deposits.
  • Replace any faulty spark plugs with the specified type.
  • Check ignition coils for resistance using a multimeter; replace any that are out of spec.
