what causes my Ford Mustang S650 (2024-Present) to stall while driving?

Solution

1. Preparation

• Gather tools and parts needed for repairs.
• Disconnect the battery to prevent electrical shorts during repairs.

2. Fuel System Inspection

• Tools Required: Fuel pressure gauge, safety goggles.
• Sub-steps:
  1. Locate the fuel rail and connect the fuel pressure gauge.
  2. Turn on the ignition without starting the engine and observe the pressure reading; it should be within specifications.
  3. If pressure is low, check the fuel pump, fuel filter, and fuel injectors for blockages or failures.
  4. Replace any faulty components as necessary.

3. Ignition System Check

• Tools Required: Multimeter, socket set, torque wrench.
• Sub-steps:
  1. Remove the spark plugs and inspect for wear or carbon buildup; replace if necessary.
  2. Use a multimeter to test the ignition coils for proper resistance; replace any faulty coils.
  3. Reinstall the spark plugs with the manufacturer's recommended torque specification.

4. Throttle Position Sensor (TPS) Replacement

• Tools Required: Screwdriver set, multimeter.
• Sub-steps:
  1. Locate the TPS on the throttle body.
  2. Disconnect the electrical connector and remove the screws holding the TPS in place.
  3. Install the new TPS and reconnect the electrical connector.
  4. Use a multimeter to verify the TPS voltage output is within specifications.

5. Air Intake System Cleaning

• Tools Required: Air intake cleaner, soft brush.
• Sub-steps:
  1. Remove the air filter and inspect for dirt or debris; replace if necessary.
  2. Clean the air intake ducts and throttle body using air intake cleaner and a soft brush.
  3. Reassemble the air intake system securely.
