My transam is running rich and feels like it's not running on all 8 cylinders.

Hi limo1644, Welcome to 2carpros and TY for the donation
Probable causes of an engine running rich are as follows:
1.Fuel pressure not within specs.Can be cause by restricted fuel return line or defective fuel pressure regulator.
2.Defective Oxygen Sensors.
3.Leaking injectors.
4.Coolant temperature sensor out of calibration.
5.Restricted air intake system.
