Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Replace Air Filter
  • Locate the air filter housing.
  • Remove the screws or clips securing the air filter cover.
  • Take out the old air filter and inspect it; replace it if dirty.
  • Install the new air filter and secure the cover back in place.
3. Clean Throttle Body
  • Locate the throttle body (usually between the air intake and the intake manifold).
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
  • Reassemble the air intake duct securely.
4. Replace Spark Plugs
  • Remove the ignition coil cover if present.
  • Disconnect the ignition coils and unbolt them from the engine.
  • Remove the old spark plugs using a spark plug socket and ratchet.
  • Check the gap on the new spark plugs and adjust if necessary.
  • Install the new spark plugs and reconnect the ignition coils.
5. Check Fuel System
  • Attach a fuel pressure gauge to the fuel rail's service port.
  • Turn the ignition to the "ON" position without starting the engine and check the fuel pressure reading.
  • If the pressure is below specifications, consider replacing the fuel pump or inspecting the fuel filter for blockage.
