Very high idle
I have a 94 s10 it has very high idle and it increases when i apply the brake. could it be the brake booster? if it is can i just disconnect the hose and plug it or will my truck brake down?

Probably is brake booster if you can hear hissing sound, would not advise disconnecting hose, would be extremely hard to stop the vehicle, a dangerous situation. also check for vaccum leaks on intake manifold. follow brake booster hose to engine and check for leak from there
