You are going to have to be more specific than that. What do you mean it is out? Also your cat has nothing to do with your oil pressure.

How did you decide the cats were the problem? Its a 00 camaro? Hows your fuel pressure and so on. Ls car are notorious for fouling the #8 plug because of the biuldup in that injector.

So your driver side cat isnt working right. Check your plugs and wires on that side while your at it. You get this code when the air mearued before the cat hasnt changed enough by the end of the cat. It doesnt explain why you are dropping off in power though, unless the cat is clogging. Is it stumbling at 4k all the time or after you get the code?

The code is dropping the car into dummy loop or limp mode or what ever you want to call it, so you dont hurt it. Clear the code and see how it drives. It wont fix the cat that is going bad but it should pic the performance up again until the next load cycle throws the code again.
