Need some help Please,, I got Po130 and PO135 code. I got a new bosch O2 sensor from Fcp. Installed it and codes came back, reset and tried it 3 times. Any suggestions???
side note, the side tit on the new O2 sensor was opposite of the original.
I called Fcp and had them check the other ones in stock, they were the same. I filed it down to install. wire colors matched (black, grey, white, white)

I have a 95 glt non turbo

Thanks, Bill, NJ

 

How does the connector and the wiring that belongs to it look?

 

the wiring is fine, I still don;t know why the plugs are backwards. Fcp checked all the ones they had in stock , and they were all the same. I drive 20 miles and the ce comes back on.
