I called the service center and they said there is nothing they could do for me since its over 80k miles. Im going to try the 800 number on Monday morning and hope for a bit more help from them.Call Nissan, and i'm sure they will take care of you. Call the 1800 nissan number, Good luck.
I have new O2 sensors below the cats, but that's it. Should I put a K&N filter? I'll clean the MAF sensor today. I thought it was the cats because there is a rattle under the drivers side that cat and I had to replace my IPMD and from what I've read it can cause the cats to go bad... Is that correct?Your other numbers are very good. Hard to see that being just a bad cat.
If it was a bad cat I would excpect the other numbers to be high as well. High NO is somemes due to running lean like lazy/bad O2 sensors, a dirty MAF sensor, or dirty/bad EGR. Do you have a K&N or other "high flow" filter? Have you cleaned the MAF sensor, PCV valves, and throttle body yet?
No don't get a k&n, they make it worse.I have new O2 sensors below the cats, but that's it. Should I put a K&N filter? I'll clean the MAF sensor today.

Throttle body and PVC, is that something I can handle on my own without much experience? I looked it up and it doesn't seem to hard
