Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety during repairs.
2. Address Fault Codes
  • Use the OBD-II scanner to retrieve and document the trouble codes.
  • Research the specific codes for targeted diagnosis and repair.
3. Inspect and Replace Components

A. Ignition System

  • Tools Required: Socket set, torque wrench
  • Remove the engine cover if necessary.
  • Disconnect the electrical connectors from the ignition coils.
  • Remove the ignition coils using the socket set.
  • Inspect spark plugs for wear; replace them if they are worn out or fouled.
  • Reinstall new ignition coils and reconnect electrical connectors.

B. Air Filter

  • Open the air filter housing.
  • Remove the old air filter and replace it with a new one.
  • Ensure the housing is sealed properly upon reassembly.

C. Fuel System

  • Tools Required: Fuel pressure gauge
  • Connect the fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position (do not start the engine) to check pressure readings.
  • If pressure is low, inspect the fuel pump and fuel injectors for functionality; replace as necessary.
4. Reset the Check Engine Light
  • After repairs, reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear the error codes from the system.
