[QUOTE="Gilaguy23, post: 436609, member: 19498"] I'm gonna take a stab at this one for you although I'm not familiar with the TBI systems. Older vehicles,mostly carbed, ran a hot air intake system into the air inlet which typically was under the snorkel of the air cleaner. There was a vacuum motor in there that when cold closed the fresh cold air intake and opened a path that drew heated air of the exhaust manifold to create a faster warm up thus less smog from the cold running rich. Id bet that black tube you see is hooked up to the exhaust manifold. or should have been. Personally Id try to hook it back up if im correct. [/QUOTE]
