Interesting codes to be related to the catch can, a leak that big that could cause lean codes should be fairly noticeable in you engine bay. What type of catch can was this ?
and like somebody else said, make sure your drain is fully closed, you should be able to hear the hissing if it was that bad, if this fails, put the stock hose back in the PCV and intake tract, disconnect the battery for about 2 minutes or so, then take her for a drive and see if you can replicate the issue.
