I've got a 1987 Mustang 5.0, AOD transmission. Someone before me did a smog pump delete, I don't really think they did it properly but that's something for another day. I have two vacuum lines that I'm not quite sure where they belong. I'm assuming that one belongs on part of the smog system that's gone, but looking at vacuum diagrams is just a struggle for me, and Youtube videos aren't much help either. My car runs, but doesn't run well at all. It idles a little bit rough, and after a couple minutes will idle up to around 2000 RPM and begin going up even more from there. where do these vacuum lines belong, or should i plug them somehow? I'm not sure. My car still has the EGR system despite the smog pump's removal. any help is greatly appreciated. i put a picture of me holding each line, and a picture of where they enter the vacuum tree or whatever it's called.
