Solution

1. Preparation

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

2. Replace Air Filter

Locate the air filter housing.
Open the housing by releasing any clips or screws.
Remove the old air filter and clean the housing.
Install the new air filter, ensuring it fits snugly in place.
Reassemble the housing and secure it.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter (consult the service manual for exact location).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a line disconnect tool.
Remove the old filter and install the new filter in the correct orientation.
Reconnect the fuel lines and replace the fuse before starting the engine.

4. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing them and disconnecting the electrical connector.
Use a spark plug socket to remove old spark plugs.
Check the gap on the new spark plugs using a gap tool and adjust if necessary.
Install new spark plugs and torque them to the manufacturer's specifications (usually around 13-15 lb-ft).
Reinstall the ignition coils, securing them properly.

5. Clean Throttle Body

Disconnect the throttle body from the intake manifold.
Use throttle body cleaner and a soft brush to clean the throttle plate and inside the housing.
Reassemble the throttle body, ensuring all gaskets are in good condition.
Reconnect the electrical connectors.
