Hi jason tate, Welcome to 2carpros and TY for the donation

Sounds like its running too rich could be caused by the following below

1. Excessive fuel pressure can be cause by restricted fuel return line or defective fuel pressure regulator.
2. Defective Oxygen Sensors.
3. Leaking injectors and fuel pressure regulator.
4. Coolant temperature sensor out of calibration.
5. Restricted air intake system.

So how do you fix the above problems, especially #2?
