Last night as I left my friends cousin house, my check engine light came on, so I went to my friends house to read the code. I dont remeber the actual code it gave me, but it said " Secondary Air Injection System Control B Circuit Low" Which I believe is code P2259 when I googled it. I really dont know what this means and I was actually wondering if its going to cause any problems to my rx-8. If theres a solution to this please let me know. Thanks for your help.

 

Get us the code. We can not guess as to what the issue is.

 

Just go to any Autozone and they will do it for free.
