Hello everyone so I was looking over the engine bay of my 1993 Bronco 5.8L, because I am having some engine rpm problems (Already made a post in regards). As a result of this issue the engine rpm raises and lowers significantly while in gear and idle. Today I was pulling out of my drive way and the car had shifted gears as a result of the rpms raising (despite me not touching the throttle). when I reached the end of the drive way the breaks lost all compression and a break line broke due to the pressure as the car was fighting to move forward. Thankfully I was able to get the car back to its parking spot and when I looked under the hood to inspect what had happened I noticed there was a vacuum line disconnected. I am unsure where this line is suppose to be connected which is my question for you all! I have made a short Youtube video to show the route and the line itself. I have looked at vacuum line diagrams however I can't seem to understand them. Any help would be appreciated!!!
