Grand Marquis 97 slow acceleration

When at full stop it used to pick up speed fine. Couple of weeks ago It had to be jump started. The guy raved up the engine real hard after that. After that the car almost dies when I accelerate it from a full
stop (say at the stop signal), but after that it runs fine and accelerates ok till the next stop.
Do you know what could be causing it and how could it be fixed.
Thanks in advance.
