Solution
1. Preparation
  • Gather tools and parts.
  • Disconnect the negative battery terminal to ensure safety.
2. Inspect and Replace Ignition Components
  1. Remove Ignition Coil:

    • Unscrew the bolts holding the ignition coil in place.
    • Gently pull the ignition coil out of the spark plug well.
  2. Replace Spark Plug:

    • Use a spark plug socket to remove the spark plug from cylinder 2.
    • Inspect the old spark plug for damage; replace with a new spark plug if necessary (gap to specification).
    • Install the new spark plug and torque to manufacturer specifications (typically around 13-15 lb-ft).
  3. Reinstall Ignition Coil:

    • Place the ignition coil back into the spark plug well.
    • Secure it with the bolts and reconnect the electrical connector.
3. Fuel Injector Inspection and Cleaning
  1. Remove Fuel Injector:

    • Disconnect the fuel line and electrical connector from the injector.
    • Remove the retaining clips and pull the injector out of the rail.
  2. Clean or Replace Injector:

    • If cleaning, use an appropriate fuel injector cleaner and follow the manufacturer's instructions.
    • If damaged, replace the injector with a new one.
  3. Reinstall Injector:

    • Insert the cleaned or new injector back into the fuel rail.
    • Reconnect the fuel line and electrical connector securely.
4. Final Checks
  • Reconnect the negative battery terminal.
  • Start the engine and allow it to idle to ensure smooth operation.
