Solution

1. Preparation

• Gather all tools and parts needed for the repair.
• Disconnect the battery to avoid electrical shorts or shocks.
• Allow the engine to cool before starting any work.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 2:
  • Use a socket set to unbolt the coil from the engine.
• Remove the spark plug:
  • Use a spark plug socket to carefully unscrew and remove the spark plug.
• Inspect the spark plug for wear, cracks, or carbon buildup.
• If necessary, replace the spark plug with a new one, ensuring it matches the manufacturer's specifications (typically a heat range of 16).
• Torque the spark plug to the manufacturer's specified value (usually around 13-15 lb-ft).

3. Inspect and Replace Ignition Coil

• If the ignition coil shows signs of damage:
  • Remove the old ignition coil and replace it with a new one.
  • Torque the ignition coil bolts to the manufacturer’s specifications (generally around 7-10 lb-ft).

4. Inspect and Clean Fuel Injector

• To check the fuel injector:
  • Disconnect the fuel injector connector and remove the injector from the fuel rail.
• Clean the injector using a fuel injector cleaning kit or replace it if necessary.
• Reinstall the injector and ensure it is securely connected.

5. Final Assembly

• Reattach the ignition coil and any other components removed during the process.
• Reconnect the battery.
