If I can't figure out what's wrong I am gonna take it to my Buddy that did my efi live and see if he can figure it out.

I have been catless for over a month now and it ran perfect till this problem so I don't think it has anything to do with taking out the cats. I had the 2 rear O2s turned off aswell.
