Solution
1. Preparation
  • Gather tools and parts needed for repair.
  • Ensure the engine is cool and disconnect the battery.
  • Tools Required: OBD-II scanner, socket set, torque wrench, cleaning supplies (throttle body cleaner), multimeter.
2. Clean Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
  • Ensure the throttle plate moves freely and is not obstructed.
  • Reattach the air intake duct securely.
3. Replace Spark Plugs and Ignition Coils
  • Remove the engine cover if applicable.
  • Disconnect the electrical connectors from the ignition coils.
  • Use the socket set to remove the ignition coils and spark plugs.
  • Install new spark plugs, ensuring they are torqued to the manufacturer’s specifications (usually around 13-15 lb-ft).
  • Reinstall the ignition coils and connect the electrical connectors.
4. Check Fuel Pressure
  • Locate the fuel pressure test port on the fuel rail.
  • Connect a fuel pressure gauge and turn the ignition key to the "ON" position without starting the engine.
  • Observe the pressure reading; it should meet manufacturer specifications (typically 50-60 psi).
  • If pressure is low, inspect the fuel pump and filter for issues.
5. Inspect Vacuum Lines
  • Visually inspect vacuum hoses for cracks, breaks, or disconnections.
  • Replace any damaged hoses with OEM parts.
  • Ensure all connections are tight and secure.
6. Clean or Replace MAF Sensor
  • Disconnect the electrical connector from the MAF sensor.
  • Remove the sensor from the intake duct.
  • Clean the MAF sensor with MAF cleaner. If damaged, replace with a new sensor.
