Check Engine Code P2A00

During the installation process, I had to remove the passenger side header to remove one of the stock cats. It was tightened to spec however during reinstallation and a new gasket was used. I did notice that the car has seemed intermittently sluggish with acceleration for the last few weeks.

Any suggestions would be appreciated. Should I be driving the car?
