Solution

1. Preparation

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

2. Inspect and Clean Throttle Body

Remove the intake hose connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reattach the intake hose securely.

3. Replace Air Filter

Open the air filter housing by unclipping or unscrewing it.
Remove the old air filter and inspect its condition.
Install a new air filter, ensuring it is seated properly and the housing is sealed.

4. Check and Replace Spark Plugs

Remove the ignition coil cover if applicable.
Disconnect the ignition coils and unbolt them from the cylinder head.
Use a spark plug socket to remove old spark plugs; inspect for wear or carbon buildup.
Install new spark plugs with the recommended gap (typically 0.043 inches for Honda engines) and torque to the manufacturer’s specifications (usually around 13 lb-ft).

5. Test and Replace MAF Sensor (if necessary)

Disconnect the MAF sensor and remove it from its housing.
Inspect for dirt or damage; clean with MAF cleaner if needed.
If the sensor is faulty, replace it with a new one, ensuring correct orientation during installation.
