I bought my 00 i30 and as I was driving it home the SES light came on with code p0138. I popped the hood and noticed the plug for the 02 sensor wasn't connected. Plugged it in, reset code, all fine.

Days later light comes on again for P0140. As per another thread I replaced a fuse for Eng Ctrl and cleared code. Light off for 3 days but now is back on with same code.

Car has a slight sputter when first started up and moving. MPG kinda sucks. I have heard ECM flashes, etc. Any advice? Which one would it be below? Both bank 2 listed below are sensor 1.
