I searched and it seems like everyone has a problem just at idle. But if I slam on the brakes, esp. with auto-x, my idle almost drops out and the engine will die when either coming to a stop or close to it. It did it to me again today and it's just annoying. My booster seems fine and I just replaced the MC. This has always done it so nothing new. I have not looked at the check valve yet but could it also be a vacuum line? Thanx guys...
