1. Preparation
  • Gather tools and parts.
  • Disconnect the battery to prevent electrical shorts.
  • Ensure the vehicle is on a flat surface and securely lifted if necessary.
2. Inspect and Replace Air Filter
  • Remove the air filter housing cover using a screwdriver.
  • Take out the old air filter and inspect for dirt or damage.
  • Install a new air filter (ensure it's the correct part number).
  • Reattach the housing cover and secure it.
3. Clean Throttle Body
  • Remove the throttle body electrical connector.
  • Unbolt the throttle body from the intake manifold using a socket set.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and inside of the body.
  • Reinstall the throttle body and reconnect the electrical connector.
4. Check and Replace Spark Plugs
  • Remove the ignition coil or spark plug wires using the appropriate socket.
  • Extract the spark plugs with a spark plug socket.
  • Inspect the spark plugs for wear; replace if necessary with OEM equivalent.
  • Reinstall new spark plugs and reconnect ignition coils or wires.
5. Inspect Fuel System
  • If fuel pressure was low, check the fuel pump and filter.
  • Replace the fuel filter if it hasn’t been changed recently.
  • If necessary, replace the fuel pump with a new one, following manufacturer's specifications.
