Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Spark Plug

• Sub-steps:
  1. Remove the engine cover if applicable using a socket set.
  2. Disconnect the ignition coil connector by pressing the tab and pulling it off.
  3. Remove the ignition coil using a socket (typically 10mm).
  4. Extract the spark plug using a spark plug socket and ratchet.
  5. Inspect the old spark plug for wear and compare it with manufacturer specifications.
  6. Install a new spark plug, ensuring it is gapped correctly (refer to specifications).
  7. Reinstall the ignition coil and connect the electrical connector.

3. Test Ignition Coil

• Sub-steps:
  1. If the ignition coil is suspected to be faulty, replace it with a new one.
  2. Reconnect the ignition coil connector after installation.
  3. Clear the codes using the OBD-II scanner.
  4. Start the engine and monitor for misfire codes.

4. Inspect and Clean Fuel Injector

• Sub-steps:
  1. Remove the fuel rail if necessary to access the fuel injector.
  2. Disconnect the electrical connector and fuel line from the injector.
  3. Remove the injector from the rail.
  4. Clean the injector using an appropriate cleaning solution or replace it if faulty.
  5. Reassemble the fuel rail and reconnect all connectors.

5. Perform Compression Test (if needed)

• Sub-steps:
  1. Remove the spark plug from cylinder 1.
  2. Insert a compression tester into the spark plug hole.
  3. Crank the engine to obtain a compression reading.
  4. Compare results with manufacturer specifications; replace the engine if compression is low.
