Ok so I just got done putting together my 91 integra with a b18a1. And I was having trouble with some lines on the throttle body. Theres a suction line that controls my throttle response. But I can't find out what it connects to. Or what type of lines I should use. And theres another line coming off the back of the block. Which is for oil or something. I can't remember what my friend told me. It's a line running off the crankshaft casing. And I was wondering what these lines hook up to?? I have been looking all over the place and can't seem to find out what they go to. And I was wondering if anyone else had ran into thise problem?? Cause I really need the help the car idles from a range of 500 to 2k due to the suction line missing. So any help would be awesome. Thanks.
