3 months ago I had a misfire so I replaced the plugs wires, and o2 after the cat. Today I got this code. No change in drivability. Any ideas?

You can try cleaning the MAF sensor. Also, maybe try ohming out the injectors to see if one or more are clogged.

Post cat O2 sensor doesn't affect fueling. The O2 sensor in the rear manifold is for AFR.
