Solution

Solution

1. Preparation

  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Allow the engine to cool down before beginning work.

2. Inspect and Replace Ignition Components

  1. Remove Engine Cover: Use a socket set to remove any screws or bolts holding the engine cover in place.
  2. Inspect Spark Plug:
    • Remove the spark plug from Cylinder 2 using a spark plug socket.
    • Check for signs of wear, carbon buildup, or damage.
    • If necessary, replace with a new spark plug that meets manufacturer specifications (check gap settings).
  3. Inspect Ignition Coil:
    • Disconnect the electrical connector from the ignition coil for Cylinder 2.
    • Remove the ignition coil using a socket set.
    • Test the coil with a multimeter to ensure it is functioning correctly; replace if faulty.

3. Check and Replace Fuel Injector

  1. Fuel Injector Removal:
    • Disconnect the fuel line after relieving the fuel pressure (consult service manual for procedure).
    • Remove the fuel injector connector and bolts holding the injector in place.
    • Carefully extract the fuel injector from Cylinder 2.
  2. Inspect and Test Injector:
    • Check for clogs or damage; clean or replace the injector as necessary.
    • Ensure it is properly seated and connected upon reinstallation.

4. Conduct Compression Test

  1. Compression Test Setup:
    • Remove spark plug for Cylinder 2 and install a compression tester.
    • Crank the engine to obtain a reading.
    • Compare the reading to manufacturer specifications; if low, further investigation may be needed for internal engine issues.

5. Reassemble and Reconnect

  • Reinstall any components removed (ignition coil, spark plug, fuel injector).
  • Reconnect the battery terminal.
  • Start the engine and check for any recurring codes or issues.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
