Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the battery to ensure safety during repairs.
2. Address Airflow Issues
  • Remove the air filter housing:
    1. Use a socket set to remove the screws or clamps securing the housing.
    2. Take out the old air filter and inspect for dirt or damage.
  • Replace the air filter:
    1. Install a new air filter that meets OEM specifications.
    2. Reassemble the air filter housing and secure it with screws/clamps.
3. Check Fuel Delivery
  • Inspect fuel pressure:
    1. Connect a fuel pressure gauge to the fuel rail.
    2. Turn the ignition to the "ON" position (do not start) to check pressure readings.
    3. If pressure is below specifications (consult service manual), replace the fuel pump.
  • Replace fuel filter (if applicable):
    1. Locate the fuel filter in the fuel line.
    2. Use line wrenches to disconnect the fuel lines and remove the old filter.
    3. Install a new fuel filter in the correct orientation.
4. Clean Throttle Body
  • Remove throttle body:
    1. Disconnect electrical connectors and vacuum lines.
    2. Use a socket set to remove the throttle body bolts.
  • Clean throttle body:
    1. Spray throttle body cleaner inside the throttle body and use a soft brush to remove carbon buildup.
    2. Wipe clean with a lint-free cloth before reinstallation.
  • Reinstall throttle body:
    1. Secure with bolts and reconnect all electrical connectors and vacuum lines.
5. Inspect and Replace Spark Plugs
  • Remove spark plugs:
    1. Use a spark plug socket and ratchet to carefully unscrew the spark plugs.
  • Inspect for wear or fouling:
    1. Check the gap and condition of each spark plug.
  • Install new spark plugs:
    1. Use a torque wrench to tighten to the manufacturer's specified torque (consult service manual).
