why does my Ford Mustang S550 (2015-2023) feel like it's losing power?

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, throttle body cleaner.
• Safety Warnings: Disconnect the battery before working on electrical systems.

2. Address Fault Codes

• If error codes indicate specific components (e.g., oxygen sensor, mass airflow sensor), replace them as necessary.
• Clear the codes from the ECU after repairs.

3. Replace Air Filter

• Remove the air filter housing cover using a socket set.
• Take out the old air filter and inspect for dirt or damage.
• Install a new air filter and reassemble the housing.

4. Inspect and Replace Fuel Components

• Using a fuel pressure gauge, connect it to the fuel rail and check for pressure.
• If pressure is low, replace the fuel pump and filter:
  • Relieve fuel system pressure.
  • Disconnect the battery.
  • Remove the fuel pump access panel (if applicable) and replace the pump and filter.
  • Reconnect everything and check for leaks.

5. Inspect and Replace Ignition Components

• Remove spark plug wires and inspect spark plugs for wear or fouling.
• Replace any faulty spark plugs and coils as identified in the diagnostics.

6. Clean Throttle Body

• Remove the intake duct and access the throttle body.
• Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
• Ensure that the throttle body operates smoothly without sticking.
