Solution

1. Preparation

Tools Needed: OBD-II scanner, socket set, multimeter, fuel pressure gauge, basic hand tools.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before performing any inspections.

2. Address Engine Codes

Use the OBD-II scanner to retrieve any stored error codes.
Document the error codes and research potential causes related to stalling.
Clear the codes and perform a test drive to see if they reappear.

3. Inspect and Replace Fuel Filter

Tools Required: Socket set, fuel line disconnect tool.
Steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
2. Disconnect the battery.
3. Locate the fuel filter, typically along the fuel line.
4. Use the fuel line disconnect tool to remove the fuel lines from the filter.
5. Remove the fuel filter and install the new one, ensuring the flow direction matches the markings.
6. Reconnect the fuel lines and battery.

4. Test and Replace Ignition Components

Tools Required: Multimeter, socket set.
Steps:
1. Inspect spark plugs for wear; replace if they are fouled or worn.
2. Test ignition coils with a multimeter for proper resistance.
3. Replace any faulty ignition coils.
4. Reassemble any components removed during inspection.

5. Inspect Air Intake System

Tools Required: Basic hand tools.
Steps:
1. Visually inspect the air intake hose for cracks or disconnections.
2. Clean or replace the air filter if dirty.
3. Ensure the intake manifold is sealed properly and there are no vacuum leaks.
