Basically, a misfire is when a cylinder should fire at a certain time, but doesn't.
As for the whistling noise, I agree that it sounds like a vacuum leak. And since it only happens when the brake pedal is down, I'm still going to say it'* the brake booster.
PontiacDad - The master cylinder doesn't have a vacuum line going to it, the vacuum line goes to the brake booster, which the master cylinder is mounted to.

The vacuum line goes to the booster only. Might try a little vaseline on the inside of the connection at the manifold vacuum source and the booster. I hear they're expensive to replace.

Those are probably used or china. Not something I'd put in my brakes. And that doesn't count installation, Which is a b****. My papers say to quote an hour and a half to R&R one.

crazy *** night
So i am driving back from my trip about 80 miles from home.
Temp guage starts getting hot..hotter... then drops so i think mmkay
then hot again and just drops back to normal
So about 30 miles later it gets as hot as past the Red mark so i stop on the shoulder, get it towed, very annoying gettin towed 50 miles .
Doesnt even start now, the oil pressure guage is like at zero lol.
