Message	yo i tried what you said. i unplugged the hose from the plenum to the brake booster, i plugged up the plenum end and the hose that was unplugged. i started my car and it idled fine. i pressed the brake pedal, which felt much stiffer and my rpm's were NOT dropping. the car wasn't dying, everything was good. rpm's stayed consistant and my boost gauge was right at -20, not even vibrating like it used to. so...you're saying this means the brake booster is bad? if so, i hear it's a pain in the ass to remove. why is that? i've done all deletes on my z, transmission removal and plenty of plenum pulls. how hard would you compare it to say...a plenum pull? thanks dude. i appreciate it.
