1988ragtop

Can anyone help me, i've got an 88gt that was kicking out a lot of black smoke. I changed the EGR valve and put in all new spark plugs, my black smoke went away and car ran ok for a couple of day with a little bit of hesitation. Now as soon as the car start is sputters and dies on me. I put in a new fuel filter about 6 months ago. Any other suggestions?

Run codes if ya have a reader if not go down to Autozone and get them to read them for you, pull the plugs and tell us what color they are, check vaccum hoses, and timing.

The ignition switch could be bad.......
