That sentence just blew my cranial processor. Try erasing all the stored codes and see what comes back. Some could be old stuff so start fresh.

yeah sorry never was good with punctuation i cleared the codes everytime and reset the KAM a few times the only CM code is the insufficent egr flow i also have been having charging issues and noticed that i get more codes when the battery light is on so im thinking the voltage spikes may have something to do with it so new alternator is on the way to hopefully fix that and then start fresh and go from there but i sure hope i can get it figured out soon this is driving me nuts

Bad alt. can make everything look crazy. Keep your eye on the replacement. Alot of these are crappy out of the box. If the voltage problem is still there, or returns after a week or three, don't cross it off the list as a possible culprit.
