how to address the P0301 misfire code in my Honda CR-V Sixth Generation (2023-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.

2. Replace Spark Plug

• Remove the engine cover if applicable.
• Locate and remove the spark plug wire or ignition coil for cylinder 1.
• Use a spark plug socket to remove the spark plug from cylinder 1.
• Inspect the electrode for wear or fouling; replace it if necessary.
• Install a new spark plug, ensuring the gap is set to manufacturer's specifications (typically 0.044 inches).
• Torque the spark plug to the manufacturer's specification (usually around 13-16 lb-ft).

3. Inspect and Replace Ignition Coil (if needed)

• If the ignition coil was found faulty during diagnostics, remove it from cylinder 1.
• Install a new ignition coil, ensuring it clicks into place securely.
• Reconnect the spark plug wire or connector to the new ignition coil.

4. Check and Clean Fuel Injector

• If the fuel injector is found to be faulty, remove it from cylinder 1.
• Clean the injector using a dedicated fuel injector cleaner or replace it if clogged or damaged.
• Reinstall the cleaned or new fuel injector and ensure all connections are secure.

5. Reassemble and Reconnect Battery

• Reinstall any components you removed during the repair process.
• Reconnect the battery terminals, ensuring they are tight and secure.
