this is funny

i already fixed this problem, had it taken in a shop but i still cant figure out why....had no brakes cuz my booster was goin out and whenever id come to a stop my engine would studder or die and then itd start right back up when i cranked it. as soon as i had my booster and practically a whole new brake system installed it quit.

How is that funny? It makes perfect sense. Your booster is directly hooked up to intake vaccum. If it is leaking your engines vaccum is compromised. Which would make it idle like crap, if at all.

Yep you was loosing all your vacuum pressure through your busted brake booster then when it was replaced no more vacuum leak thus a better running engine.
