why does my Ford Mustang S650 (2024-Present) feel like it has no power when accelerating

Solution

1. Preparation

• Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, vacuum gauge, multimeter.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool before beginning any work.

2. Address Fault Codes

• Use the OBD-II scanner to retrieve any stored trouble codes.
• If codes indicate a specific issue (e.g., P0300 for misfires), follow appropriate repair procedures for that code.

3. Fuel System Repair

• Tools Required: Fuel pressure gauge.
• Connect the fuel pressure gauge to the fuel rail.
• Turn the ignition key to the "ON" position (without starting the engine) and check the pressure reading against manufacturer specifications.
• If low, check fuel pump relay and fuses, then replace the fuel pump if necessary.

4. Air Intake Cleaning

• Remove the air filter and inspect for dirt or obstructions.
• Clean or replace the air filter as needed.
• Inspect and clean the throttle body using throttle body cleaner and a soft cloth.
• Reassemble the intake system securely.

5. Ignition System Inspection

• Remove spark plugs using a socket set and inspect for wear or fouling.
• Replace spark plugs if they are worn or damaged.
• Test ignition coils with a multimeter for proper resistance; replace any faulty coils.

6. Exhaust System Check

• Inspect the exhaust system visually for dents or blockages.
• If a catalytic converter blockage is suspected, conduct a backpressure test using a vacuum gauge.
• Replace the catalytic converter if backpressure is excessive.
