Yep. Like Cliff said, the fact that it shut off indicates the leak isn't severe, And, aside from knowing it won't get better by itself, that much of a leak won't affect the operation of the Secondary Port Throttles (SPT as it is referred to).

The "Right of Passage" for any ZR-1 pilot is a plenum pull. So much stuff is under the plenum that sooner or later you'll want to do a "walkabout" under there. When you do, a Mitivac (hand-held vacuum pump from Harbor Freight (or the like) will come in handy to isolate the source(s).
