Hello out there,
This part is on the front top of the engine (90' 420 SEL) next to the Idol Control Valve. IT has two male tubes protruding and one has broken off. the tubes go to plastic vacume hoses. I need to order a new part but don't know what its called.
Thanks
PS...would this part have anything to do with rough surging idle?

I believe its a thermo vacuum valve for emmisions.I diabled mine,and plugged vacuum line.Spray water,or carb spray around vacuum ports,and manifolds,on a running engine.If idle changes you know where your leak is.
