Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal.
2. Clean the 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 areas.
  • Reassemble the intake duct securely.
3. Replace Air Filter
  • Locate the air filter housing and open it.
  • Remove the old air filter, ensuring no debris falls into the intake.
  • Install a new air filter, ensuring it fits snugly in the housing.
4. Inspect and Replace Spark Plugs
  • Remove the ignition coil assembly (if applicable) to access the spark plugs.
  • Use a spark plug socket to remove the old spark plugs.
  • Check the gap of the new spark plugs and ensure they meet manufacturer specifications.
  • Install the new spark plugs and reconnect the ignition coils.
5. Check Fuel Pressure
  • Connect a fuel pressure gauge to the fuel rail service port.
  • Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading against manufacturer specifications.
  • If the pressure is low, inspect the fuel pump and filter for issues.
6. Inspect for Vacuum Leaks
  • Visually inspect all vacuum hoses connected to the intake manifold.
  • Perform a smoke test if necessary to identify hidden leaks.
  • Replace any damaged hoses or seals.
