Q: Acceleration problems on 2001 Mercury Grand Marquis

When I lightly press the gas pedal at 30-60 mph my mercury will shake and shutter slightly as if it is not getting a good flow of fuel or some plug or wire is bad. It is a jerking feeling. Anyone with advice would be greatly appreciated. Thanks
