...what is a little plastic tank ...
My guess: its surge tank; verification for that needs a pic from you. Or you have to clic clic clic uself via 'Favorite links' on page below...
Surge Tank:
V6 air intake is divided on two sections after TB. The intake manifold has an interconnecting channel, which is opened at WOT. In there is a valve flap(s), operated with vacuum pwr actuator. Actuator located on one side of manifold. Vacuum is stored into the tank in question, just to ensure full operation of the mentioned actuator, at your request.
Engine warm, push gas pedal TB mech by hand momentarily WOT and watch... ECU opened Air valve opens vacuum channel from the surge tank to the actuator, actuator lever can be seen moving... compare to page 3 link below , VGE Pwr valve circuit.
