If your inj. is set up as mine is, the crack was on the top of the throttle body opening area. There is a rubber fitting recieving 3 vacuum lines & plugs into the top, with a plastic 'snap' to hold it on....... the plastic snap holder was hiding the crack. My car would stall first thing in the morning, ( I mean, just shut off), then I would start it up again, and it was fine for most of the day, after getting up to temp..
