Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge, vacuum gauge.
  • Disconnect the negative terminal of the battery to ensure safety before starting repairs.
2. Addressing Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Record any diagnostic trouble codes (DTCs) and research their meanings.
  • Clear the codes and note if they reappear after testing.
3. Inspecting the Air Intake System
  • Remove the air intake duct using a socket set to access the throttle body.
  • Check for debris or obstructions in the air filter and replace if necessary.
  • Inspect the intake manifold for vacuum leaks using a vacuum gauge.
4. Checking Spark Plugs and Ignition Coils
  • Remove the engine cover (if applicable) using the socket set.
  • Pull out each spark plug and inspect for wear or fouling; replace if worn.
  • Test ignition coils with a multimeter for proper resistance; replace faulty coils.
5. Examining the Fuel System
  • Use a fuel pressure gauge to check the fuel pressure at the rail; compare with manufacturer specifications.
  • If low, check the fuel pump and filter for clogs or failures; replace as necessary.
6. Testing the Idle Air Control Valve (IACV)
  • Locate the IACV, usually near the throttle body.
  • Disconnect the electrical connector and test with a multimeter for proper function.
  • Clean the IACV with throttle body cleaner if dirty; replace if faulty.
