I had these codes once. Ended up it was a vacuum leak in one of those tinny hoses in the engine bay, which by all means in not normal! I would suggest that you look for that hole and any other holes fix them and see if the code goes away. GL And by the way the one that had a hole in it for me was the one for the CAM aka pain in the *** to replace wraps around whole engine ![Sad](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_sad.gif)

Their is a pipe that a mechanic just rigged because he said that it had a hole in it and that was normal for these cars
