He told me today he had capped off all the holes left from the lean burn/smog equipment. I was thinking he just wanted to cap it off to prevent any vacuum issues. I'm not all familiar with how it all works, but I did hook the system back up when I got the car. I replaced the old valve and hooked the hose back up to it, which was plugged up using a bolt from a previous owner. Not sure what they were doing with the car, my guess was a poor man's lean burn delete lol, but I'm not sure.
