Deleted cats and ses light I deleted my cats and of course the ses light is on and it's dumping fuel, don't really have the cash for a tune right now. Will o2 sims make the car run better or just shut off the ses light?

If you can find sims, they'll trick the computer into thinking the cats are still there. The main manufacturer of the sims just got into some hot water with the EPA about making them. So, they may become hard to find.
However, the rear O2's shouldn't really have much of an affect on fueling from what I understand. The front O2's are used for AFR feedback to the PCM. Are you sure you don't have an exhaust leak that may be causing a false lean reading on the O2's?
