Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery cable to ensure safety.

2. Inspect and Replace Spark Plugs

Remove the ignition coil cover using a socket set.
Disconnect the ignition coils from the spark plugs and remove them.
Inspect the spark plugs for wear or fouling, and replace if necessary.
Reinstall the new spark plugs and ignition coils, ensuring they are torqued to the manufacturer’s specifications (typically around 13 lb-ft).

3. Check and Replace Fuel Filter

Locate the fuel filter in the fuel line (refer to the service manual for exact location).
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using the appropriate line removal tool.
Replace the filter with a new one, ensuring proper orientation, and reconnect the fuel lines.

4. Inspect and Replace Air Filter

Open the air intake housing and remove the air filter.
Inspect for dirt and debris; if dirty, replace with a new air filter.
Reassemble the air intake housing securely.

5. Test Fuel Pump Functionality

Use a fuel pressure gauge to check that the fuel pressure is within specifications (typically 30-40 psi for most engines).
If pressure is low, replace the fuel pump located in the fuel tank.
