I have seen some reports somewhere having the PedalPot exchanged on the 4200 as well.
Only difference with the 3200GT is a less exited response of the ECU.
Mechanically its the same Bosh unit used on the 3200, only with a different orderingnumber and probably different internal resistorvalues.
We are investigating possibilities converting the PP to contactless and at this moment an old unit is researched by the factory who does the TB's as well.
Problem is to find a solid mechanical method of mounting the new parts in a quite narrow place.
I suspect mine too; sometimes less responsive to pedal actions, recovering after some quick flooring 3 or 4 times (ignition off) thus wheeping the resistortracks.
It is a common faillure on modern cars though, nothing Maserati special.
Ah, sorry, I was thinking along the lines of the 3200 throttle body potentiometer, rather than pedal potentiometer. So does the 4200 not have a potentiometer in the throttle body?
Guys...for us lesser mortals........any pics or diagrams to support this debate?!!....

Boomerang has just done a pic by pic post of the 3200 pedal pot

Just wondered whether we have anyone who has had one replaced , and what the symptoms were when it was failing, still i have a bit of a lazy throttle , battery reset and an energetic drive sorts it out to a degree but it should be sharper

FD drive-by-wire module is the quickest fix, no lazy behaviour in v aggressive mode.
To be fair though, I always felt the same without the mod, felt I needed to do the battery outage and spirited drive to get it 'right' again.
Don't forget after the battery reset to allow 10 mins of idling before driving. This period of 'learning' is required (or so I have been informed a number of times).
