Any Suggestions? 1988 Mustang LX 2.3L, Black Smoke when loaded?

I have been having problems my car shooting black smoke, losing all power, and chugging when it get loaded up. What could cause this?

I have a brand new MAP sensor, ECT, injectors, TPS, and plugs in it.

any suggestions?

Is the problem at idle only? What's your fuel pressure at?

I recommend picking one of these up to check for codes and run a self test:

the fuel pressure is the one thing that i'm not sure, and its the one tool that i dont have here.

its possible to check codes without spending thirty bucks for a special tool. with a wire and a test light, i pull three codes on the KOEO test but they deal with the egr valve. but mine isnt in my car, its blocked off. so i expected that.
