Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery to ensure safety during repairs.

2. Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket
• Remove the engine cover if applicable.
• Locate the spark plug for cylinder 1 (consult service manual for location).
• Using a spark plug socket, remove the old spark plug.
• Inspect the spark plug gap; replace if out of specification.
• Install a new spark plug and torque to manufacturer specifications (typically 13-15 lb-ft).

3. Replace Ignition Coil

• Tools Required: Socket set, torque wrench
• Disconnect the electrical connector from the ignition coil.
• Remove the mounting bolts and carefully pull the ignition coil out.
• Install the new ignition coil and secure it with bolts to manufacturer specifications.
• Reconnect the electrical connector.

4. Test Fuel Injector

• Tools Required: Fuel pressure gauge, multimeter
• Disconnect the fuel injector connector.
• Use a multimeter to check the injector's resistance (should be within manufacturer specifications).
• If faulty, replace the fuel injector by removing the retaining clips and pulling it out of the rail.
• Install the new injector, ensuring a proper seal, and reconnect the electrical connector.

5. Verify Cylinder Compression

• Tools Required: Compression tester
• Remove the spark plug from cylinder 1.
• Insert the compression tester and crank the engine a few times.
• Record the compression reading and compare it to manufacturer specifications.
• If the reading is low, further investigation into the engine's internals may be required.
