Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the negative battery cable to ensure safety while working on electrical components.

2. Inspect and Replace Ignition Components

• Tools Required: Socket set, torque wrench, spark plug socket, ignition coil puller
• Remove the ignition coil from cylinder 1.
  • Unplug the electrical connector from the ignition coil.
  • Remove the mounting bolts using the socket set.
  • Carefully pull the ignition coil out.
• Inspect the spark plug condition.
  • Remove the spark plug using the spark plug socket.
  • Check for signs of wear, fouling, or damage. Replace if necessary.
• Install a new spark plug and torque to manufacturer specifications (typically around 13-15 lb-ft).
• Reinstall the ignition coil and secure it with the mounting bolts. Reconnect the electrical connector.

3. Inspect and Clean Fuel Injector

• Tools Required: Fuel injector cleaner, fuel line removal tool
• Disconnect the fuel line from the injector while using caution to avoid fuel spray.
• Remove the fuel injector from cylinder 1.
• Clean the injector using a fuel injector cleaner or replace it if it is faulty.
• Reinstall the fuel injector and reconnect the fuel line securely.

4. Compression Test (if necessary)

• Tools Required: Compression tester
• Remove the spark plug from cylinder 1.
• Install the compression tester in the spark plug hole.
• Crank the engine and record the compression reading.
• Compare the reading to the manufacturer's specifications. If low, further diagnosis may be needed for internal engine issues.
