Need help Engine code P2270
I am getting the check engine code P2270. When I look it up online is says [FONT=Arial][SIZE=1][FONT=Arial][SIZE=1]
P2270 O2 Sensor Signal Stuck Lean (Bank 1 Sensor 2). Can anyone help me with what I need to do about this. I have an aftermarket Alta downpipe and exhaust and not sure if that is affecting it. Any help would be greatly appreciated.
Thanks
