Oldsmobile/Buick Repair: CAR TROUBLE, black ash, foot on the gas


Question
MY 95 2.3L OLDS ACHEIVA. IT'S BLACK SMOKE COMING
OUT THE TAILPIPE, CHECK ENGINE LIGHT AND THE COOLING FAN TURNS ON ALL AT THE SAME TIME.
THE CAR RUNS POORLY AND THE TAILPIPE IS COVERED WITH BLACK ASH LOOKING STUFF. WHAT COULD BE WRONG,
IS IT SERIOUS OR JUST MINOR. PLEASE HELP

P.S WHEN I SAY THE CAR RUNS POORLY I MEAN WHILE I'M DRIVING WITH MY FOOT ON THE GAS IT SLOWS DOWN
FOR MAYBE 3 SECONDS AND GOES BACK TO NORMAL, IT DOES IT WARM OR COLD.
I GOT THE CAR MAYBE 9 MONTHS AGO AND NEVER HAD A
TUNE UP, TWO MONTHS AGO I HAD A NEW FUEL PUMP PUT
IN AND THE CAR RAN GREAT FOR A MONTH OR SO NOW IT'S RUNNING POORLY.
