three things, if your idle hangs enough to drive like an auto, its probably not the vacuum but your iac, the easiest way to find vacuum leaks is to get a can of carb clearner and (trying not to set the car on fire) spray it around common area's like the throttle body, vacuum connectors until you spray in on area and the idle changes. And third, throw some comma's in your writing, I'm no english major but damn that was hard to read.
