So I recently got a CEL for p2187. Too lean at idle. Someone told me my O2 sensor is hooked up incorrectly(bought the car earlier this month). Here’s a pic. Is this wrong?? Should I switch just the two plugged into the downpipe, or do I also swap the plugged-in part at the top of the picture?
only thing is, I’m turbo back.. straight pipe no cats. So could a incorrect O2 sensor even be the reason for this code?

It should be black to black and grey to grey.

Ok so the top portion is plugged in correctly, but is the two sensors going into the downpipe correct? Someone very credible told me they are swapped.

They look reversed.
The one that's clipped into the bracket, I have that one going to the first sensor on the O2 housing.
