Solution
1. Preparation
  • Gather necessary tools and parts before starting the repair.
  • Disconnect the negative battery terminal to ensure safety while working on the engine.
2. Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Take out the old air filter and inspect the housing for debris.
  • Install the new air filter, ensuring it is seated properly.
  • Reattach the air filter housing cover securely.
3. Check and Replace Spark Plugs
  • Remove the ignition coil by unscrewing the retaining bolts.
  • Disconnect the electrical connector from the ignition coil.
  • Unscrew and remove the old spark plug using a spark plug socket.
  • Inspect the spark plug gap and condition; replace if necessary.
  • Install the new spark plug and torque to manufacturer specifications (typically 13-15 lb-ft).
  • Reinstall the ignition coil and reconnect the electrical connector.
4. Clean the Throttle Body
  • Disconnect the throttle body electrical connector and the intake hose.
  • Use throttle body cleaner and a clean cloth to remove carbon buildup inside the throttle body.
  • Reattach the intake hose and electrical connector securely.
5. Fuel Pressure Check and Replacement
  • Attach the fuel pressure gauge to the fuel rail test port.
  • Turn the ignition to the "On" position (do not start the engine) and check the reading against manufacturer specifications.
  • If fuel pressure is low, inspect the fuel pump and replace if faulty.
  • Reconnect all lines and ensure there are no leaks.
