why does my Ford Mustang S650 (2024-Present) exhaust smell like rotten eggs?

Solution

1. Preparation

• Tools Required: OBD-II scanner, jack and jack stands, socket set, multimeter, safety goggles, gloves.
• Allow the vehicle to cool down before starting work. Disconnect the battery to ensure safety.

2. Addressing the Catalytic Converter

1. Remove the Catalytic Converter:

   • Lift the vehicle using a jack and secure with jack stands.
   • Locate the catalytic converter and remove the bolts securing it to the exhaust system using a socket set.
   • Carefully detach the catalytic converter from the exhaust pipes.

2. Inspect and Clean:

   • Check the catalytic converter for any signs of physical damage or clogging. If damaged, replace it.
   • If the converter appears blocked, consider cleaning it with a catalytic converter cleaner or replace it.

3. Fuel System Inspection

1. Check Fuel Pressure:

   • Connect a fuel pressure gauge to the fuel rail to measure pressure. Refer to the manufacturer specifications for normal values.
   • If pressure is low, inspect the fuel pump and filter for blockages and replace as necessary.

2. Inspect Fuel Injectors:

   • Remove fuel injectors and inspect for clogs or leaks. Clean or replace injectors if necessary.

4. Oxygen Sensor Replacement

• If the diagnostic steps indicated faulty oxygen sensors, locate the sensors in the exhaust system.
• Remove the sensors using a wrench and replace with new units. Ensure they are tightened to manufacturer specifications.

5. Reassemble and Test

• Reattach the catalytic converter and exhaust pipes, ensuring all bolts are secured to the correct torque specifications.
• Reconnect the battery and start the vehicle, allowing it to reach operating temperature.
