I had a cat delete done on my 2003 350z with straight pipes run all of the way back. My service engine soon light came on a couple days later. I just had the codes read and it says starter relay switch and manufacture mode switch along with the o2 and a couple other things. Could this all be caused from the cat delete? If not what problems might I start encountering based on these codes? Any insight would be appreciated. Thanks in advance.

 

Adam,

I don't recognize those code descriptions. Do you have the DTC numbers?
