Well I don't think having cats could be an issue. The rear o2's have nothing to do with engine mangagment, and the front o2's aren't affected by cats or the lack thereof.
But I have o2 sims for the hell of it. I might do a full tune up just for the hell of it. How long should that take me? The car was two times worse today, I felt like I was on a bronco.
It also seems like it's worse when the car is cold. Once it warms up it seems to get better. Is this a trait of a certain problem.
