Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shocks.
Ensure the vehicle is on a flat surface and properly secured with jack stands if lifting is required.

2. Check and Replace Fuel Filter

Locate the fuel filter (usually found along the fuel line).
Use a socket set to disconnect the fuel lines carefully, ensuring to catch any fuel in a container.
Replace the old fuel filter with a new one, ensuring the direction of flow is correct.
Reconnect the fuel lines securely and check for leaks.

3. Inspect and Replace Air Filter

Open the hood and locate the air intake assembly.
Remove the cover to access the air filter; take out the old filter.
Install a new air filter, ensuring a snug fit.
Reassemble the air intake cover and secure it.

4. Test and Replace Throttle Position Sensor (if needed)

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the sensor using a screwdriver.
Install the new TPS by aligning it properly and securing it.
Reconnect the electrical connector.

5. Inspect Spark Plugs and Ignition Coils

Remove the ignition coils using a socket set.
Take out the spark plugs using a spark plug socket and inspect them for wear or carbon buildup.
Replace worn spark plugs with new ones, ensuring the gap is set correctly (typically 0.043 inches for Honda).
Reinstall the ignition coils securely.
