Unfortunately I can't view anything I log right now because I only have access to a Mac, my Pc is at work and I wont be working for awhile. I do have a catch can installed. Were you able to open the older log file I posted (cruise WOT)? I was having issues posting before but changed it to a zip file as per your recommendation.

what vehicle is this?
May have excessive oil build up in the intake manifold, time to clean it out or wait for it to burn off and hope the catch can keeps more from building up.
