Solution

1. Preparation

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

2. Fuel System Inspection

Sub-steps:
1. Locate the fuel rail and connect the fuel pressure gauge.
2. Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure.
3. If pressure is below specifications (refer to the vehicle's service manual), inspect the fuel pump and filter for clogs or failures.
4. Replace the fuel filter if it appears dirty, and consider replacing the fuel pump if it fails to operate correctly.
Tools Required: Fuel pressure gauge, socket set.

3. Ignition System Repair

Sub-steps:
1. Remove the engine cover if necessary to access spark plugs and ignition coils.
2. Inspect spark plugs for excessive wear or fouling and replace them if necessary (specification: typically NGK or Motorcraft spark plugs).
3. Check the ignition coils for cracks or signs of failure. Replace any faulty coils.
Tools Required: Socket set, spark plug socket, torque wrench.

4. Throttle Body Cleaning

Sub-steps:
1. Disconnect the air intake duct from the throttle body.
2. Use throttle body cleaner and a soft cloth to clean carbon deposits from the throttle body.
3. Reconnect the air intake duct and ensure all clamps are secure.
Tools Required: Throttle body cleaner, cloth, screwdriver.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle, monitoring for any stalling or rough running.
