Reading the numbers
Across the 18 model years of the Mercury Grand Marquis in this data, 2002 draws comparatively few complaints; 2005 is the outlier year.
Filings have fallen off, 8 in the last three years against 10 in the three before. That is normal as a generation leaves the road.
The median odometer reading at the time of complaint was 50,000 miles.
In owners' own words
2002 Mercury Grand Marquis lunges forward (increase rpm @1000, and loud growl from engine compartment) when I let off the accelerator, I.E. Approaching a stop light. Once I release the brake and accelerate again, all goes back to normal. There is no "check engine" light, and no other notable problems. It is intermittent and annoying.

While driving vehicle off of carwash conveyor, the engine raced to full speed. I had to us both feet on the brake, and shift into neutral to stop the car. With the front tires locked, the car still accellerated over two speed bumps before stopping. Vehicle speed control · reported at 40,000 miles
Cruise control was set at 65mph on the vehicle. Cruise control would not disengage manually or when brake pedal was applied. Speed increased to 75mph before emergency brake was applied to stop vehicle. Mercury dealer was notified. *Ak *scc Vehicle speed control
