my citroen zx judders and blows black soot/smoke out of exhaust ??help

I have a "k "reg citroen zx, that when it starts up it blows black smoke out of the exhaust which forms as a kind of soot on the floor, also whilst driving it judders as if running out of fuel even though it is'nt. at first i though it was because of dirt in the carb but seems clean, it drives fine apart from the juddering but judders all the time even at high speeds and no matter what gear your in. can anyone help and let me know what could be goingwrong.
