What would make my car pull off slowly? on 1991 Buick Park Avenue

The car rides smooth once it's moving but you have to hit the gas really hard to get it moving.

If it were a manual transmission I would say a bad clutch, it is most likely an automatic transmission so you may have a transmission problem, an accelerator cable that isn't opening the throttle fully. Perhaps a loss of full fuel pressure or volume.
