It needs fixing in any event, but the stalling out is because of the huge vacuum leak caused by the defective booster. As for whether that is also affecting the modulator vacuum, I tend to think not. If it lowered the manifold vacuum THAT severely- the engine would be running VERY poorly due to the lack of vacuum. I would think.

Could the trans modulator go bad from getting wet?
