Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a flat surface and ensure the engine is cool.
  • Disconnect the negative battery cable for safety.
2. Replace Air Filter
  • Locate the air filter housing.
  • Open the housing by unscrewing or unclipping it.
  • Remove the old air filter and inspect for dirt or damage.
  • Install the new air filter, ensuring a snug fit.
  • Reassemble the air filter housing.
3. Fuel Pressure Check
  • Attach the fuel pressure gauge to the fuel rail service port.
  • Turn the ignition key to the "On" position without starting the engine.
  • Observe the pressure reading; it should match the manufacturer's specifications.
  • If pressure is low, check the fuel pump and fuel filter for issues.
4. Clean Throttle Body
  • 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.
  • Ensure the throttle plate moves freely and reassemble the duct.
5. Inspect and Replace Ignition Components
  • Remove the engine cover if necessary.
  • Inspect spark plugs for wear; replace if necessary (specify gap settings).
  • Test ignition coils using a multimeter; replace any that are out of specification.
  • Reinstall all components securely.
6. Verify MAF Sensor Functionality
  • Disconnect the MAF sensor electrical connector.
  • Clean the MAF sensor with MAF cleaner.
  • Reconnect the sensor and clear any codes from the engine control unit (ECU) using the OBD-II scanner.
