ok i recently replaced my engine with a used one from attarco. when putting the engine in we broke this thing on the back of the intake manifold. i have called dealers and everything but no one can identify this part (sorry i dont have pics) ok here goes....obviously it screws into the back of the intake manifold. it has three vaccum lines; two small ones that attach to the vsv that is attached to the fire wall (i think this one is only on california cars that are equiped with a/c thats what the vaccum diagram says) the third is bigger and it attaches to the throttle body. on the back it has a plastic screw and spring. ok as for what it does im not exactly sure but im pretty sure its for adjusting the idle because we plugged off the hole and the car runs like shit but when u open it the idle comes up and it smoothes out....what the hell is this part does anyone have a part # mabey??
