ZL1 Check Engine Light

[SargeantSarcasm]

I have been hearing a "leaking noise" coming from the area by the pedals...shortly after this I got a check engine light. I had onstar run a diagnostic on it and they said it was something to do with the fuel management system. I brought the car into my local chevy dealership as the car is under warranty with no modifications. They just called me back saying that they cannot find any hardware problems, they updated the software, and they are still getting the check engine light. Has anyone else had a similar issue? Sounds like a vacuum hose to me but they said its fine.
