Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the electrical components.

2. Replace Fuel Filter

Locate the fuel filter, usually found along the fuel line.
Use a socket set to remove the filter. Be cautious of fuel spillage.
Install the new filter, ensuring the flow direction matches that of the old filter.
Reconnect any clips or brackets previously removed.

3. Replace Spark Plugs and Ignition Coils

Remove the engine cover if necessary to access the ignition coils.
Disconnect the electrical connectors from the ignition coils.
Remove the bolts securing the coils using a socket wrench and pull the coils out.
Remove old spark plugs using a spark plug socket and replace them with new ones, ensuring they are torqued to the manufacturer’s specifications (usually around 13-15 lb-ft).
Reinstall the ignition coils and reconnect the electrical connectors.

4. Clean or Replace Air Filter

Open the air intake housing by loosening the clamps with a screwdriver.
Remove the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it is seated correctly.
Reassemble the air intake housing securely.

5. Test and Reconnect Battery

Reconnect the negative terminal of the battery.
Start the engine and let it idle to check for any immediate issues.
