TPS determines the position of the throttle plates and the rate at which they're opening or closing. That much is simple.
The information it provides to the ECU is taken in conjunction with gear and rpm to determine the ignition map and the EXUP positioning. That's not so simple.
I believe that disconnecting the TPS makes the ECU default to a basic pre-set map for ignition and EXUP, most probably based on just gear and rpm alone. I could be wrong, though.
The reason I suggested disconnecting it was to eliminate the possibility of false signals from a faulty TPS from causing your ECU to set inappropriate or randomly changing values which might - stress, might - cause the stutter you're experiencing.
To be honest, I don't think the TPS is at fault but by getting you to disconnect it, I was hoping to set your mind at rest on that.
