my Ford Mustang S650 (2024-Present) won't accelerate properly what could be the issue

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Air Intake System

• Tools Required: Socket set, screwdrivers
• Sub-steps:
  1. Remove the air intake duct by loosening the clamps and disconnecting any electrical connectors.
  2. Check the air filter for dirt and obstructions; replace if necessary.
  3. Inspect the intake manifold for any cracks or loose connections; repair or replace as needed.
  4. Reinstall the air intake duct securely and reconnect electrical connectors.

3. Inspect Fuel System

• Tools Required: Fuel pressure gauge, safety glasses
• Sub-steps:
  1. Connect the fuel pressure gauge to the fuel rail service port.
  2. Turn the ignition to the "ON" position without starting the engine and check the fuel pressure reading against manufacturer specifications.
  3. If pressure is low, check the fuel pump, fuel filter, and fuel lines for issues.
  4. Replace any faulty components as necessary.

4. Throttle Body Cleaning

• Tools Required: Throttle body cleaner, soft cloth, socket set
• Sub-steps:
  1. Remove the throttle body assembly by unscrewing it from the intake manifold.
  2. Clean the throttle plate and interior walls using throttle body cleaner and a soft cloth.
  3. Reinstall the throttle body, ensuring it is tightly secured and all connections are reattached.

5. Check Ignition System

• Tools Required: Spark plug socket, multimeter
• Sub-steps:
  1. Remove the spark plugs using a spark plug socket and inspect for wear or carbon buildup.
  2. Replace any damaged spark plugs with new ones, ensuring they are gapped correctly.
  3. Test the ignition coils with a multimeter for proper resistance and replace any faulty coils.
