what are common causes of misfires in Honda Pilot Third Generation (2016-present)

Solution

1. Preparation

• Gather required tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Spark Plugs

• Remove the engine cover if necessary.
• Using a socket and ratchet, carefully remove the spark plugs.
• Inspect each plug for wear and replace them with OEM or high-quality aftermarket plugs.
• Torque the new spark plugs to the manufacturer's specification (usually around 13-15 lb-ft).

3. Check and Replace Ignition Coils

• Remove the ignition coil connectors.
• Unscrew the ignition coils using a socket set.
• Inspect each coil for cracks or signs of wear.
• Replace any faulty coils with new ones, ensuring they are seated correctly and secured with the proper torque.

4. Inspect and Clean Fuel Injectors

• Use a fuel injector cleaning kit or have them professionally cleaned if clogged.
• Replace any defective injectors with new ones.
• Reinstall injectors ensuring proper alignment and secure fittings.

5. Air Intake System Inspection

• Check for any vacuum leaks in hoses connected to the intake manifold.
• Inspect the air filter and replace if dirty.
• Ensure the throttle body is clean; if necessary, clean it using throttle body cleaner.

6. Compression Test

• Reconnect the battery terminal.
• Remove spark plugs and install a compression gauge into each cylinder.
• Crank the engine and record the compression readings.
• Compare values to manufacturer specifications; if low, further investigation into internal engine components is required.
