Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Disconnect the battery to ensure safety during the process.
  • Allow the engine to cool down before starting.
2. Replace Spark Plugs
  • Remove the engine cover if applicable.
  • Disconnect the electrical connectors from the ignition coils.
  • Remove the ignition coils using a socket set.
  • Extract the old spark plugs with a spark plug socket.
  • Install new spark plugs, ensuring they are gapped correctly to manufacturer specifications.
  • Reinstall ignition coils and reconnect electrical connectors.
3. Check and Replace Air Filter
  • Open the air filter housing.
  • Remove the old air filter and inspect for dirt or damage.
  • Install a new air filter, ensuring it fits snugly in the housing.
  • Close the air filter housing securely.
4. Inspect and Repair Vacuum Leaks
  • Visually inspect all vacuum hoses for cracks or disconnections.
  • Use a smoke machine or carburetor cleaner to detect vacuum leaks around the intake manifold.
  • Replace any damaged hoses or gaskets found during inspection.
5. Fuel System Check
  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "On" position (without starting) to check the pressure reading.
  • If the pressure is below specifications, consider replacing the fuel filter or fuel pump as needed.
