why does my Honda CR-V Sixth Generation (2023-present) engine misfire while driving

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Replace Spark Plugs

• Tools Required: Socket set, torque wrench, spark plug gap tool.
• Remove the ignition coil cover if applicable.
• Carefully remove each spark plug using the socket set.
• Inspect the old spark plugs for wear and compare them against specifications.
• Install new spark plugs, ensuring the correct gap is set.
• Torque the spark plugs to the manufacturer's specifications (typically 13-15 lb-ft).

3. Inspect and Replace Ignition Coils

• Tools Required: Socket set, multimeter (if testing).
• Remove the ignition coils from the engine, carefully disconnecting any electrical connectors.
• Test each ignition coil with a multimeter for proper resistance; replace any defective coils.
• Install new ignition coils, making sure they are seated properly and reconnect electrical connectors.

4. Check Fuel System

• Tools Required: Fuel pressure gauge, safety glasses.
• Connect the fuel pressure gauge to the fuel rail and turn the ignition key to the ON position (do not start the engine).
• Check the fuel pressure reading against manufacturer specifications.
• If pressure is low, inspect the fuel pump, filter, and injectors for blockages or failures.
• Replace any failing components as necessary.
