Solution

1. Preparation

• Gather necessary tools and parts before starting.
• Disconnect the vehicle battery to ensure safety.
• Allow the engine to cool if recently operated.

2. Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the engine cover if necessary.
• Locate the spark plug in cylinder 1.
• Use the spark plug socket to unscrew the old spark plug and remove it.
• Inspect the new spark plug for any defects.
• Install the new spark plug, tightening it to the manufacturer’s specifications (typically around 13-15 lb-ft).

3. Inspect and Replace Ignition Coil

• Tools Required: Socket set, multimeter (for testing).
• Remove the ignition coil from cylinder 1 by unscrewing it.
• Use the multimeter to test the resistance of the ignition coil; it should match manufacturer specifications.
• If the ignition coil is faulty, replace it with a new one and securely fasten it in place.

4. Test and Clean Fuel Injector

• Tools Required: Fuel injector cleaning kit or professional cleaning service.
• Remove the fuel injector from cylinder 1.

• If necessary, clean the injector using a fuel injector cleaning kit or replace it with a new one.
• Reinstall the fuel injector and ensure it is seated properly.

5. Perform Compression Test

• Tools Required: Compression tester.
• Remove the spark plug and ignition coil from cylinder 1.
• Insert the compression tester into the spark plug hole.
• Crank the engine and record the compression reading.
• Compare the reading to manufacturer specifications; if low, further diagnosis of the valve or piston is required.
