Black exhaust smoke?

I dont know if it happens while i am driving, but when i parked my car last night, i quickly floored it a couple times. when i did this, a bit of black smoke came out the tail pipe. I dont know why this would be…almost everything under the hood is new…plugs, wires, cap and rotor, oil, sensors, gaskets…i use fuel inj. cleaner every so often. The only thing left is the fuel pressure regulator, but i dont know how to test it. Does that seem like it could be the culprit? or does it sound like something else? thank you

Oh, its a 1989 thunderbird with a 3.8 V6 and 120,000 miles

thats just soot from the exhaust.if its running good,i wouldnt worry about it.just about every car you see today has a black tailpipe,look at some of them,when You Get the chance,but if you havent already,you might try and change the 02 sensor.i have a 88 olds,3.8 and the fuel pump regulator is a sealed unit and all you can do is check for vacuum and hook up a fuel pump tester and check for pressure and voluum.
