Hey guys i got a check engine light pop up for mutiple o2 sensor codes. i already have the bank 1 sensor 1 o2 with the blue connector and it says i need bank 2 sensor 1 and bank 2 sesnor 2. i hear you dont really have to worry about the down streams

its the upstreams that are more important but my car has aftermarket headers so its gets hot and must throw off some misfires because the obd2 sayed multiple misfire detection and the sensors sit right in front of the engine so its even more heat so does anyone know the the part number for the sensors?

And i bought a new bosche 02 sensor on ebay lookes exactly like the one i had on the car and for some reason when we installed it the car started idling rough like it was about to stall so we put back the old crapy one maybe it was defective i don't know so i bite the bullet and spent 114 dollars at pep boys for the same exact on haven't installed it yet though i could have sworn bosche was the oem brand for these things am i wrong?

First...your headers or not don't make a difference on your misfires. Get your misfires fixed first. Then you can look to address your O2 sensor codes.

Do you have any misfire codes?

I just realized you already made a post for this. Stick to one post.
