The elbow is not cracked. Seems like a vac leak, but an off iacv would present it self like this too. I'll see if fuel trims are off while open throttle. I don't think so and I'm getting good fuel mileage. So could be a vac leak when the throttle plate closes and vac pressure is very high at that moment. Maybe this is why I don't see it in the smoke test. Also, I bet it's not a huge rupture bc then my idling would be off. Misfires, etc. been there done that.
