First question, what motor is it? Heck is it even a Fiero? Your not goign to get much help without asking questions with at least some details.

Be like me saying what colour is my hair? Without you ever seeing what I look like.

Well spitting black from a 2.8 is an over fuel issue.

First thing to check is coil and a tune up.

Next up is check for a bad O2 sensor, the best way to do that is to check with a scan tool. However you are over there and I am over here, so I can't help with my scan tool.

I would give the car a good tune up and see if that helps.

Overfuel is caused by too much gas or not enough spark.

The O2 sensor controls how much fuel and the Coil, Pickup Coil, Ignition Module control the spark.
