Solution

1. Preparation

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

2. Replace Fuel Filter

Locate the fuel filter, which is typically near the fuel tank or along the fuel line.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Use a line wrench to disconnect the fuel lines from the filter.
Remove the mounting bolts and take out the old fuel filter.
Install the new fuel filter in the correct orientation.
Reconnect the fuel lines securely and reinstall the fuel pump relay.

3. Replace Spark Plugs

Remove the engine cover if applicable to access the spark plugs.
Using a spark plug socket, remove the old spark plugs one at a time.
Inspect the old plugs for wear and compare them to the new ones.
Apply a small amount of anti-seize lubricant on the threads of the new spark plugs.
Install the new spark plugs and torque them to the manufacturer's specifications (typically around 12-15 lb-ft).
Reattach the ignition coils and engine cover.

4. Inspect and Repair Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or propane torch to detect leaks around the intake manifold and vacuum lines.
Replace any damaged hoses and reseal any leaking gaskets as necessary.
