Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the vehicle battery to ensure safety while working on the ignition system.

2. Inspect and Replace Spark Plug

• Sub-steps:
  1. Remove the engine cover (if applicable) using a socket set.
  2. Disconnect the ignition coil connector for cylinder 2.
  3. Remove the ignition coil by unscrewing it from the cylinder head.
  4. Remove the spark plug using a spark plug socket.
  5. Inspect the spark plug for wear; replace it if necessary with a new one (OEM recommended).
  6. Reinstall the new spark plug and torque to manufacturer specifications (usually around 18-22 lb-ft).

3. Check and Replace Ignition Coil

• Sub-steps:
  1. Test the ignition coil with a multimeter for resistance (consult the manual for specifications).
  2. If defective, replace the ignition coil with a new one (ensure compatibility with model).
  3. Reconnect the ignition coil connector and ensure it is seated properly.

4. Inspect and Replace Fuel Injector

• Sub-steps:
  1. Disconnect the fuel injector connector for cylinder 2.
  2. Remove the fuel injector from the fuel rail (may require fuel rail removal).
  3. Clean or replace the fuel injector with a new one if faulty.
  4. Reinstall the fuel injector and ensure all connections are secure.

5. Conduct Compression Test

• Sub-steps:
  1. Remove all spark plugs to allow for easier cranking.
  2. Insert the compression gauge into cylinder 2 spark plug hole.
  3. Crank the engine and record the compression reading.
  4. Compare the reading to manufacturer specifications; replace the engine if readings are low.

Tools Required:

• OBD-II scanner
• Socket set
• Multimeter
• Compression gauge
• Torque wrench
• Fuel injector removal tool

Parts Required:

• Spark plug (OEM recommended)
• Ignition coil (if faulty)
• Fuel injector (if faulty)

Estimated Repair Time: 2-4 hours

Safety Warnings:

• Disconnect the battery before working on electrical components.
• Allow the engine to cool before removing any components.
