Solution
1. Preparation
  • Gather tools and parts.
  • Disconnect the battery to ensure safety.
  • Allow the engine to cool before working on components.
2. Inspect and Replace Spark Plug
  • Sub-steps:
    1. Remove the engine cover if applicable.
    2. Disconnect the ignition coil connector for cylinder 1.
    3. Remove the ignition coil from cylinder 1.
    4. Remove the spark plug using a spark plug socket.
    5. Inspect the spark plug for wear or damage; replace if necessary.
    6. Gap the new spark plug to the manufacturer’s specifications (0.028-0.031 inches).
    7. Install the new spark plug and torque to 15 lb-ft (20 Nm).
    8. Reinstall the ignition coil and connector.
3. Check and Replace Ignition Coil
  • Sub-steps:
    1. If the spark plug is fine, test the ignition coil for cylinder 1 using a multimeter.
    2. If faulty, disconnect the battery again.
    3. Remove the ignition coil from cylinder 1.
    4. Install a new ignition coil, ensuring it is seated properly.
    5. Reconnect the ignition coil connector.
4. Inspect and Clean Fuel Injector
  • Sub-steps:
    1. Disconnect the fuel injector connector for cylinder 1.
    2. Remove the fuel rail if needed to access the injector.
    3. Inspect the fuel injector for clogs or damage; clean or replace it as necessary.
    4. Reinstall the fuel injector and reconnect the fuel rail and connectors.
5. Compression Test (if necessary)
  • Sub-steps:
    1. Remove the spark plug for cylinder 1.
    2. Insert a compression tester into the spark plug hole.
    3. Crank the engine and read the compression level; it should be within manufacturer specifications (typically around 150-200 psi).
    4. If compression is low, further diagnostics may be required for internal engine issues.
