A P1131 is a faulty oxygen sensor (Bank 1 Sensor 1) i believe, you reverted back to the stock y pipe correct? only thing i can think of is the shop may of somehow messed up the o2 sensor if they were working on the midpipe (now thats big "maybe" tho)

Edit: nvm dgt got it

I only have one oxygen sensor on each side since the exhaust was put in, i turned my rear 02 sensors off, only reason i say yours is a different oxygen sensor is because the code is different, your o2 sensor is on the passenger side and probably the one that goes behind the CATS.
Did you put CATS back in?

Might just try replacing the sensors. They are cheap aren't they?

it was what i hoped it was (or atleast i think its fixed) the passenger side o2 senser wasn't plugged in all the way

SON1C · January 26th, 2012, 04:53 PM

yeah my backup was to just try replacing them but ideally didnt want to go that route lol

I didn't know they were that much. I thought like $15.
I have an extra one or two laying around I believe.
