Hello, I have a Nissan Altima P2097 code and it reads its running too rich. I had this about 6 months ago and replaced the O2 sensor and the cat and it went away but it's returned!
Any ideas? Are there numbers to check on the check engine light sensor? Or maybe a vacuum leak?

Whenever I get one of those pesky codes, I like to look here first and try some of the troubleshooting steps:

The cat should not cause that code. I would try replay the front air fuel ratio sensor with an oem one to be on the safe side. They can be temperamental
