It sounds like injectors....fuel filter....or fuel pump.....flydeep4u@Yahoo.com

Is it happening at low speed ?

I just read about this at http://consumerguideauto.howstuffworks.com/1993-to-1998-Lincoln-mark-viii-6.htm

2 issues:

Automatic transmission: Transmission shudder or vibration under light acceleration or when shifting between third and fourth gear above 35 mph can be fixed by replacing the Transmission Fluid with Mercon fluid. (1992-94)

Automatic transmission: The transmission may slip and the engine may flare when the transmission shifts into fourth gear, which can often be traced to a bad TR/MLP sensor. (1993-95)

If its happening during acceleration I'd start with the fuel filter. they are supposed to be changed every 36000 miles and most ppl dont do it. If that doesnt solve it, then you may want to think about testing the output pressure of the feul pump. If you waited too long to change the filter, you may have put too much stress on ur fuel pump . filters cost around $12
