I just corrected a vacuum leak. The valve on the bottom of my oil seperator won't close up all the way. I fixed it (took off the oil seperator for now) this morning after I found it when the truck was idling real rough and wanting to shut off. I just got these two codes 2195 and 2197 when I first started it after fixing it. I cleared them and they haven't come back but I only drove a few miles. Those codes were probably from the leak huh?
