Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during electrical checks.
Allow the engine to cool down if it has been operating.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, multimeter
Check the fuel pressure using the fuel pressure gauge. It should meet specifications for the Mustang.
If fuel pressure is low, replace the fuel pump.
Inspect fuel filters for clogs and replace if necessary.

3. Ignition System Check

Tools Required: Spark plug socket, multimeter
Remove the spark plugs and inspect for wear or fouling.
Test the ignition coils with a multimeter to ensure they are functioning correctly.
Replace faulty spark plugs or ignition coils as needed.

4. Electrical System Examination

Tools Required: Multimeter
Check the battery voltage; it should be around 12.6 volts when fully charged.
Inspect battery terminals for corrosion or loose connections; clean and tighten as necessary.
Replace the battery if it is under 12 volts or shows signs of wear.

5. Vacuum Leak Detection

Inspect all vacuum hoses for cracks, leaks, or disconnections.
Use a smoke machine or carburetor cleaner to detect leaks while the engine is running.
Replace any damaged hoses or reconnect any loose connections.
