Solution
1. Preparation
  • Gather tools and parts needed.
  • Ensure the vehicle is parked on a level surface with the engine off.
  • Disconnect the battery negative terminal to prevent electrical shorts.
2. Address Error Codes
  • Connect the OBD-II scanner and retrieve the error codes.
  • Write down the codes for reference.
  • Research the codes to determine the affected systems or components.
3. Replace Faulty Components
  • Spark Plugs:
    • Remove old spark plugs using a socket wrench.
    • Inspect for wear and replace with new spark plugs, ensuring the gap is set to manufacturer specifications (typically 0.044 inches for Honda).
  • Ignition Coils:
    • Disconnect the electrical connector and remove bolts holding the ignition coil.
    • Install new ignition coils, ensuring proper seating and reattach connectors.
4. Repair Vacuum Leaks
  • Use a smoke machine to locate and identify any vacuum leaks.
