ok as was changing the oil today and looking around i found a vacuum nipple behind the the throttle body or plenum with no line on it at all. problem is i don't know where it goes. has a bunch of vacuum behind. it looks like it goes no where under the hood maybe tranny ? i plunged it off for now seemed to idle better the whole motor is alot smoother and no more bucking up a hill. now pic is not the best took it with my phone and had a mirror on it so i could see it to take the pic. any one got any ideas.
