O2 sensors question.

[explict]

Having issues with them right now.
The green connector ones are bigger sensors. Wideband? Upstream or downstream?
The blue connector ones are smaller sensors. Narrowband? Upstream or downstream?
I thought I ordered new blue connector ones but two green connector ones came in. Took out two blue connector ones but wondering. If my tune will allow for the green ones. Ugh. I am so confused for some reason I did this like five years ago.

So just figured some info out from a friend that's a Ford tech.
DY-1039 are front sensors
DY-1038 (old pn DY-1058) are rear sensors.
I thought I was running front sensors. But some how my tune is using rear "blue" sensors. Which had me confused. Im going to order new tears and be done.
As for wideband narrowband I don't know.

There is no way you can run on rear sensors alone.
It's the front sensors which tell the PCM what it needs to do.
I replaced my front sensors with ones that I bought from Summit when I was on a road trip last year.
Bosch BCH-15716.
What issues are you having and what codes if any are you throwing?

The sensors themselves are the same, just the connectors are different. If you cut the tabs off of them they are basically interchangable, no?

The upstream sensors are bigger than the rears.

The codes I threw were O2 sensor heater malfunction.

Was the car acting funny. I'm getting similar codes right now p0135 with the car not being able to idle or drive at all because it's to rich.

Yeah the car ran like poop. Until it was warm it ran decent then. Just typical bad maf bad O2 sensor stuff. Rich lean rich lean. Mostly rich.
I don't have stock motor though.
