Solution

1. Preparation

Gather all necessary 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 spark plug wires or ignition coils.
Use a spark plug socket to unscrew and remove the spark plugs.
Inspect the spark plugs for signs of fouling or damage.
Replace with new spark plugs that meet OEM specifications (typically NGK for Honda).
Reinstall the spark plugs and reconnect the ignition components.

3. Repair or Replace Exhaust Components

If any leaks or damage are found in the exhaust system, mark the affected areas.
For small holes, use exhaust repair tape or exhaust putty as a temporary fix.
For larger damages, remove the affected section of the exhaust using a socket set.
Replace with a new OEM or high-quality aftermarket exhaust component.
Ensure all connections are secure and properly sealed.

4. Check Fuel System

Disconnect the fuel line using a fuel line disconnect tool.
Attach a fuel pressure gauge to the fuel rail and turn the ignition on (do not start the engine).
Compare the pressure reading to the specifications in the service manual. Replace the fuel pump if the pressure is low.
Reconnect the fuel line securely after testing.

5. Reassemble and Test

Reconnect the negative battery terminal.
Start the engine and listen for any abnormal sounds.
Inspect for any exhaust leaks or unusual behavior.
