Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal for safety.
  • Allow the engine to cool if recently operated.
2. Addressing Engine Codes
  • If any fault codes were stored, interpret and address them based on the manufacturer's specifications.
  • Clear the codes using the OBD-II scanner and take the vehicle for a test drive to see if they return.
3. Inspect and Clean Air Intake
  • Remove the air filter and visually inspect for dirt or blockages.
  • If dirty, replace the air filter with a new OEM part.
  • Clean the throttle body using throttle body cleaner and a soft brush.
4. Fuel System Inspection
  • Connect a fuel pressure gauge to the fuel rail.
  • Compare the reading to the manufacturer's specifications (usually between 50-60 psi).
  • If pressure is low, replace the fuel pump and filter as necessary.
5. MAF Sensor Cleaning
  • Disconnect the MAF sensor electrical connector.
  • Remove the MAF sensor from the intake duct.
  • Clean the MAF sensor using MAF sensor cleaner and allow it to dry completely before reinstalling.
6. Reassemble and Test
  • Reconnect all components and ensure all connections are secure.
  • Reconnect the negative battery terminal.
  • Start the engine and verify that it runs smoothly without stalling and accelerates properly.
