82 Cougar inline six vacuum problem

I'm having a vacuum problem. On the lower right hand side of the diagram there is a A/CL CWM (lower right of the diagram). When this is not connected to the vacuum lines the car runs great. When connected I get hesitation, stalling and really cannot drive the car that way. If you follow the lines you'll see many parts. The following are new: EGR, purge CV. The VCV and VDV are good. The unknown and don't know how to test parts are the CWM, VRDV, VRESER. I really don't understand why this is occuring or why when I leave the vacuum lines disconnected from the CWM why the car runs fine. Oh yea the carb is new as well.
