All of a sudden I've popped four o2 codes. P0161, P0155, P0141, & P0135 with mil's on both lower. Both pre cats are gutted and a full main cat. Idle is 50 percent smooth 50 percent erratic. Could I be looking at a clogged cat?

I'm running a full 3l also so I'm leaning towards a clogging cat.
Could a dirty air filter cause these symptoms.
It's the original 2.5 cat so it's been there awhile. There appears to be good flow coming out of the exhaust. I'm gonna grab a new filter and put her on in the engine bay.
Thanks for the advice Br. Looked in the book and couldn't find anything for the O2's but one I wasn't sure about listed as hego. Well checked it #13, 20 amp and it was popped. I'll be driving to work soon so I'll let you know.
