Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool before starting work.

2. Replace Spark Plug

• Remove the ignition coil from cylinder 1:
  • Unscrew the mounting bolts using a socket set.
  • Carefully pull out the ignition coil.
• Remove the old spark plug:
  • Use a spark plug socket and ratchet to unscrew and remove the spark plug from the cylinder head.
• Install the new spark plug:
  • Apply anti-seize lubricant to the threads of the new spark plug.
  • Hand-tighten the spark plug, then torque it to the manufacturer's specification (usually around 13-16 lb-ft).
• Reinstall the ignition coil:
  • Align it properly and secure it with the mounting bolts.

3. Replace Ignition Coil (if necessary)

• If the ignition coil is faulty, install a new ignition coil:
  • Remove the coil as previously detailed.
  • Install the new ignition coil in reverse order, ensuring it is seated correctly.

4. Clean or Replace Fuel Injector (if necessary)

• If the fuel injector is suspected to be clogged:
  • Remove the fuel rail to access the injector.
  • Clean the injector using a specialized cleaner or replace it if it is damaged.
• Reinstall the fuel rail and ensure all connections are secure.

5. Verify Installation

• Reconnect the negative battery terminal.
• Clear the error codes using the OBD-II scanner.
• Start the engine and allow it to idle, checking for smooth operation.
