Vac leak = Almost no brakes!
So, I reached into the ranger today to start it. (I always start when I get up, and let it warm up while I brush my teeth, GO ME) I didn't quite give it a good enough crank, so it kind of zonked out, you know how that is. This time though, the stall was followed by a "ppst" sound, and after starting, it idled like a POS. I knew a vac line blew off, but I figured I would just check it out when I got off work, for now, it ran ; so I wasn't going to be late.
At the first stoplight, I found out which line blew... Brake booster. I was doing about 60mph, and BARELY stopped before the car in front of me.
Lesson learned, when car idles crappy, see what vac line is loose before driving!
