  • o2 sensor

    Hi I keep getting the two codes bank 2 too lean, and bank 2 sensor 1 low circuit. whenever this happens the car idles a little rough like its idling too low but its not. also sometimes it hesitates a little when accelerating from a stand still.

    If i clear the codes it idles fine. but the codes will come back after some driving and it will do the same thing. I replaced that o2 sensor a few months ago already, do you think its gone bad again? Thanks!!!

    Its could have, depends what mods your running and if it is running rich it will ruin the O2's.

      ok thanks, ill clear the the codes and check the wideband and see whats goin on. it feels like it gets richer when the code is thrown but i haven't checked yet.

      as far as mods im running a turbo and methanol. shouldn't both sensors burn up if it running rich? i never had a problem with bank 1, or not yet lol. well ill check the afr and see, thanks again
