Couple questions, can you get a picture of where you found this leak? Also, did you use a smoke test to find it?
The only issue I have is if the leak was found before the air flow sensor then it would not effect the engine to cause this code. Here is a guide that will help with this:
Take a look at this info below on this code and that will help figure this out.
Also, here is a guide that will give a different way to test for a vacuum leak. Using the starter fluid method as shown is a more effective way just because it tells us when there is a leak and it effects the RPM, then that tells us it is changing the air/fuel ratio.
Let me know if you have questions. Thanks
