Solution

1. Preparation

• Gather tools and parts needed, including a spark plug socket, torque wrench, multimeter, and replacement parts (if necessary).

2. Replace Spark Plug

• Sub-steps:
  1. Locate the spark plug for cylinder 1 (usually marked; check the owner's manual for the exact location).
  2. Remove the ignition coil by disconnecting the electrical connector and unscrewing any retaining bolts.
  3. Use a spark plug socket to remove the old spark plug.
  4. Inspect the spark plug for wear; replace it with a new one if necessary, ensuring it's gapped according to manufacturer specifications.
  5. Torque the new spark plug to the manufacturer's recommended specification (typically around 15-20 Nm).

3. Replace Ignition Coil (if necessary)

• Sub-steps:
  1. If the ignition coil is faulty, install a new ignition coil for cylinder 1.
  2. Connect the electrical connector securely and ensure the coil is seated properly.
  3. Reinstall any retaining bolts.

4. Inspect and Clean Fuel Injector (if necessary)

• Sub-steps:
  1. Disconnect the fuel injector connector and remove the injector from the rail.
  2. Inspect the injector for clogs or damage; clean it with a suitable injector cleaner or replace it if required.
  3. Reinstall the fuel injector and ensure it is properly seated.
