Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Scan and Analyze

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any error codes and refer to a repair manual for specific diagnoses based on the codes.

3. Inspect Fuel System

Fuel Pressure Check:
- Locate the fuel rail and connect the fuel pressure gauge.
- Turn the ignition to the ON position without starting the engine to check pressure. It should match the manufacturer's specifications (usually around 40-60 psi for Mustangs).
- If pressure is low, check the fuel pump and fuel filter for clogs or failure.

4. Clean or Replace Components

Throttle Body Cleaning:
- Remove the air intake duct connected to the throttle body.
- Use throttle body cleaner and a soft cloth to clean the throttle plate.
- Reinstall the air intake duct securely.
Ignition System Maintenance:
- Remove the spark plugs using a socket.
- Inspect for wear; replace if necessary with OEM specifications.
- Check ignition coils for proper connection and function.

5. Inspect Air Intake

Check the air filter for dirt or blockages and replace if necessary.
Inspect the intake hoses for cracks or loose fittings.
