I went to inspect my car ,and i didn't pass the tech said o2 sensor in bank 1&2 and some vacuum line problems can any one help?

Year of engine, type, odometer? O2 you can change yourself with a new one from parts store-get a socket to wrench it out, to. Run the car for a minute or two after reaching operating temperature to help in removal. High heat helps break the rust. With some new tubing, you can also replace the vacuum lines. You get it by the foot, just match the size you need.

What where the codes? Is the car a 96 or newer?

I always get System too ritch in Bank 1

I erase the code, and I'm good for a week, or a month or two then comes back
