Help! Car Running Rich!!!!

Hello, I'm having trouble with my S197 2006 V6 mustang as all four O2 sensors are stuck on rich and coupled with this is the fact that it runs horribly and spews unburned gas and carbon particles from both exhaust pipes (aftermarket).



I've replaced the spark plugs, both upstream O2 sensors, coil pack, spark plug wires, fuel pressure regulator, MAF sensor, fuel injectors, & cleaned all of the sensor pins and connectors with electrical cleaning spray including the PCM.



The freeze frame data provided was while the car was idling with the foot off of the throttle:
