Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Take out the old air filter and clean the housing.
  • Install a new air filter ensuring it fits snugly.
  • Reattach the housing cover securely.
3. Replace Spark Plugs
  • Remove the ignition coil by unbolting it and disconnecting the electrical connector.
  • Unscrew the old spark plug using a spark plug socket and ratchet.
  • Check the gap on the new spark plugs using a feeler gauge; adjust if necessary.
  • Install new spark plugs and torque to manufacturer's specifications (typically around 13-15 lb-ft).
  • Reinstall the ignition coils.
4. Test Fuel Pressure
  • Locate the fuel pressure test port on the fuel rail.
  • Connect a fuel pressure gauge and turn the ignition key to the "On" position without starting the engine.
  • Check the reading; it should match manufacturer specifications (usually around 35-60 psi).
  • If low, inspect the fuel pump, filter, and lines for issues.
5. Inspect Vacuum Hoses
  • Visually inspect all vacuum lines for cracks or disconnections.
  • Replace any damaged hoses with new ones.
  • Ensure all connections are tight and secure.
