Bought a 1986 325es this weekend and I'm trying to get it registered and on the road. I just failed the emissions test, here are my numbers

So I've got a high NOx reading, and I also failed the fuel EVAP test. I've read that the engine running lean can cause high NOx readings, so I'm gonna start replacing vacuum lines first. Is there a way to test that the O2 sensor is reading correctly? Any advice from someone who's had these problems before? Thanks in advance.
