Vaccum problem

[88lxDCOE]

I have a vaccum problem. When I step on the brake at a light or stop sign after decelerating the revs drop real low and the car almost dies but doesnt. At a stop if I pump the brake it does the same thing. It usually only does it when its cold. I checked the one way valve to the brake booster and it looks and works fine. Other wise the car runs strong. Anybody have any ideas or similar problems?

ive had the same problem, i just thought it was the alternator, cause when the lights come on for my brakes, it drops the rpm's too. i dont know though...sorry for no help!

Oh well, doesnt matter. The DCOE's will be on hopefully in two weeks anyway. But, Never thought about the alt. Thanks.
