Solution

1. Preparation

• Gather tools and parts.

• Disconnect the battery to ensure safety.

2. Replace Spark Plug

• Remove the engine cover if necessary.
• Disconnect the ignition coil connector for cylinder 1.
• Unscrew and remove the old spark plug using a spark plug socket.
• Inspect the spark plug hole for debris.
• Install the new spark plug, tightening to the manufacturer’s torque specifications (typically around 13-15 lb-ft).
• Reconnect the ignition coil and any removed components.

3. Replace Ignition Coil

• Tools Required: Socket set, torque wrench.
• Disconnect the battery if not already done.
• Remove the ignition coil for cylinder 1 by unscrewing it from the engine.
• Install the new ignition coil, ensuring it is seated properly.
• Reconnect the ignition coil connector.

4. Inspect and Clean Fuel Injector

• Tools Required: Fuel injector cleaning kit, safety goggles, gloves.
• Disconnect the fuel injector connector for cylinder 1.
• Remove the fuel injector using the appropriate tools.
• Clean the injector using a fuel injector cleaner or replace it if faulty.
• Reinstall the fuel injector and reconnect the connector.

5. Verify Compression

• Tools Required: Compression tester.
• Remove the spark plug from cylinder 1.
• Insert the compression tester into the spark plug hole.
• Crank the engine and take the reading; compare it to manufacturer specifications.
• If compression is low, further engine diagnostics may be necessary.
