Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool down before working on it.

2. Inspect and Replace Spark Plug

• If necessary, replace the spark plug with a new one that meets OEM specifications. Torque the new spark plug to the manufacturer's recommended specification (typically around 13-15 lb-ft).

3. Inspect and Replace Ignition Coil

• If the spark plug appears in good condition, inspect the ignition coil for cracks or carbon tracking.
• Tools Required: Socket set
• Replace the ignition coil if it shows signs of damage or if the misfire persists after replacing the spark plug.
• Reinstall the ignition coil and secure it with the retaining bolts.

• Tools Required: Noid light or multimeter
• If the injector does not operate correctly, replace it. Ensure to disconnect the fuel line and use appropriate safety measures to prevent fuel spillage.

5. Reassemble and Reconnect
