anyone?

It's the dashpot. It slows the throttle closure down to avoid stalling the engine when you let off the gas.

It is unique to the TT version of the engine. The NA Stealths and 3000GT just use the ISC to provide the dashpot function where the TT has both.

The black plastic in the first two pictures is the vacuum control valve for the dashpot.
It seems to only be used on the 1G TT cars.
It's Mitsubishi part number MD614459 and runs about $192 list from the dealer. You may want to look for somebody parting out a 3000GT VR4 or Stealth RT/TT or see if the can't glue the nipple back on it.
