We picked up a code reader as well, so resetting the Codes is not as big of a deal, but it sure is irritating to see! I would do a thorough check of the upper and lower intake boots, like everyone else suggests, along with checking the three vacuum plugs at the back of the intake. The part number for vacuum caps are 11611437560 and you will need two, and 11611727176 for the larger one and there is only one of these.
If you have not been under the hood at all, I strongly recommend getting four new Torx T-40 bolts as these are sometimes stripped, or will become stripped. The part number on these are 11611440384.
As I was also doing a Cold Weather CCV, all of these lines were replaced, but I did not see any failures here. I will say that he went from using 1 quart of oil per 800-1000 miles to practically using nothing at this point once the oil separator was done. I was amazed, but not surprised at this. I am just glad that this got done before the infamous freeze up and hydrolock. Both of my ZHP's are now done.
