Chevy beretta
I have a 1994 chevy beretta and it blows out black smoke out of the tail pipe. I already replaced the coil pack. What else could it be?

Probable causes of an engine running rich are as follows:
1.Excessive fuel pressure can be cause by restricted fuel return line
2.Defective Oxygen Sensors.
3.Leaking injectors and fuel pressure regulator.
4.Coolant temperature sensor out of calibration.
5.Restricted air intake system.
