Ok, so I found the hose that is supposed to be hooked up to the BPV. It had a bolt in the end of it capping it off. I removed the bolt and hooked it up to the BPV. I started the car and everything seemed fine. As the car warmed up and the RPM's dropped to normal idle, it is idling really rough and erratic. It sounds like it wants to die, but never actually does. I give it a little gas and it's fine, but as soon as I let off and let it idle, it becomes rough again. I know a vacuum leak can make it idle rough, but don't hear any hissing anywhere to indicate a leak. I don't understand why it would run better without it hooked up to the BPV. Anyone have any ideas?
