I used to average around 20 city and almost 30 hwy when lucky, but am now averaging about 16 and 22. Wanting to know if it could be the cats or o2 sensors.

It could be either or. But being those codes are directly related to your cats, it may be more likely.
Time to do some diagnostics. |
Also what's needed to properly diagnose it? O2 sensor values while running? |
Download and install Rheingold. It has an active 02 test that can rule them out & narrow it down to your cats. |
I have a good cable. Would you be able to remotely check through teamviewer? |
Sure. Shoot me an email tomorrow. |
Are you free now? |
I am not. Open a chat session on our site. Easier for communication. |
Is there anyone that can help. I downloaded the software and operating system but I'm not able to get ahold of anyone through your websites chat or through this chat
