check engine code po422 850

Currently getting 29 mpg average and have been for several months now. I'll check the vacuum lines again and see what I find.
The cat was a complete unit from the manifold to the tail pipe of the exhaust.
What is a stand-off adapter? Not sure what you mean here. More info or a link to what you are talking about would be greatly appreciated. Thanks.
