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 battery to prevent any electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body, focusing on the interior and the throttle plate.
Reattach the air intake duct and ensure all clamps are secure.

3. Replace Spark Plugs

Remove the ignition coil(s) by unfastening the retaining bolts and disconnecting the electrical connectors.
Extract the old spark plugs using a spark plug socket and ratchet.
Install new spark plugs, ensuring the gap is set according to manufacturer specifications (typically around 0.044 inches for Honda).
Reattach the ignition coils and connectors.

4. Inspect and Replace Fuel Filter (if applicable)

Locate the fuel filter (may vary based on model specifications).
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter and remove it.
Install a new fuel filter, ensuring proper orientation and secure fittings.

5. Check Engine Mounts

Visually inspect engine mounts for cracks or wear.
If damaged, remove the bolts securing the mounts and replace with OEM parts.
Tighten to specified torque values (refer to service manual for exact values).
