one of the coolant? hoses that runs into the intake manifold is not connected. and my car wont stay at a steady idle, and i belive this is why. I need a picture to show me where this all connects. its like a 4 point metal thing. LOL. i think theres 2 vac lines. and 2 coolant lines for the intake manifold. correct me if im wrong. it idles around 2g for a while until it gets kind of high. Then once its at normal, it will idle at like 1500 for like 5 seconds then go low. then do the same thing.
