• Replace with a new ignition coil and torque to manufacturer's specification.

4. Test Fuel Injector

• Tools Required: Multimeter, fuel pressure gauge (if necessary).
• Use a multimeter to check the resistance of the fuel injector for cylinder 2 against manufacturer specifications.
• If defective, remove the fuel injector and replace it with a new one.
• Reconnect and ensure proper seating.

5. Perform Compression Test
