Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down if it has been running.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (may be integrated into the fuel pump assembly).
Use a socket set to disconnect fuel lines and remove the filter.
Install a new fuel filter, ensuring proper orientation and secure connections.
Reconnect the fuel lines and check for leaks.

3. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable) using a socket set.
Disconnect the ignition coils and remove them to access the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Install new spark plugs, ensuring they are gapped correctly per manufacturer specifications (typically 0.044 inches for Honda).
Reinstall the ignition coils and cover.

4. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth or brush to clean the throttle plate and interior surfaces.
Reinstall the air intake duct securely.

5. Inspect and Replace MAF Sensor (if necessary)

Disconnect the MAF sensor connector and remove the sensor from its housing.
Clean the MAF sensor using MAF cleaner (do not use standard cleaners).
If the MAF sensor is faulty, replace it with a new one.
