Go back and find out what the code number was. Knowing what bank is running rich would really narrow down where you have to look

The three most common causes are:
1. Mass Air Flow sensor is dirty or contaminated with air filter oil.
2.Vacuum leak.
3. Fuel pressure or delivery problem.

Pull the MAF element and clean it with MAF cleaner (NOT CARB CLEANER MAF CLEANER), check all vac hoses, and test your O2s with a torch and a multimeter. Multimeters are $7 at Harbor freight and everyone should have a basic propane torch for stuck bolts. Look up the how-tos on google.

Probably a bad O2.

Both of the 02 sensors would have had to fail at the same time, which is unlikely, but not beyond the realms of possibility...
Whatever is causing the codes, is affecting both banks simultaneously. Both the MAF and a vacuum leak are capable of doing that.

I just clean the maf sensor with the maf cleaner and it still has the light on so I'm going to change the O2 sensor next to see if that's it

Did you disconnect the battery for 15 minutes to clear the codes?

It's always something stupid... Hopefully the issue does not come back.
