why does my Ford Mustang S550 (2015-2023) lose power when accelerating

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 battery to prevent electrical shorts.

2. Inspect and Replace the Air Filter

• Remove the air filter housing cover using a socket set.
• Take out the old air filter and inspect it for dirt and damage.
• Install a new, clean air filter; ensure it is seated properly in the housing.
• Reattach the air filter housing cover and secure it.

3. Fuel System Inspection

• Reconnect the battery and turn the ignition to the "ON" position without starting the engine to prime the fuel system.
• Connect a fuel pressure gauge to the fuel rail; refer to the manufacturer's specifications for correct pressure values.
• If pressure is low, check for a clogged fuel filter or failing fuel pump; replace as necessary.

4. Ignition System Check

• Remove the spark plugs using a socket wrench; inspect for wear or carbon buildup.
• Replace any worn spark plugs with specified OEM parts (consult the owner’s manual for specifications).
• Check ignition coils for proper connection and function; replace faulty coils as needed.

5. Throttle Position Sensor Testing

• Locate the throttle position sensor on the throttle body.
• Use a multimeter to check resistance at the sensor's terminals while manually opening the throttle.
• If the resistance readings are inconsistent or outside of specified range, replace the TPS.

6. Exhaust System Examination

• Visually inspect the exhaust system for dents, kinks, or blockages.
• Check the catalytic converter for excessive heat or unusual smells.
• If blockage is detected, replace the affected components.
