You need a tune, or your o2 sensors got damaged somehow when removing or installing them back in
new exhaust - o2 sensor error codes
i just finished putting on the agency power catless downpipes and catback exhaust with hks legamax resonated midpipe and k&n intake system. I had trouble with the top o2 sensors on the removal but got them out and in the new downpipes. now when i start the car after im done it is sputtering and at times won't even start, the codes it is giving is
P1148 AND P1168 - closed loop control function bank 2 (and 1 for p1148)
P0031 AND P0038 - air fuel ratio sensor 1 heater bank 1 (and 2 for p0038) control circuit low
anyone have any ideas on what i should do?
i dont know if this means my o2 sensors are toast or im not sure if its due to the catless downpipes and the incorrect tune, any help is appreciated

awesome, thank youBoulder Nissan or call Scott at Fontana Nissan.
i've just sent your tune, but you defo need to replace the sensors first, don't worry it can be quite common for them to go when removing from oem cats. sensors could be cheaper here ? http://www.courtesyparts.com/gtr-parts-r35...012-c-7727.htmlyeah thats what i figured, where i am in canada sucks though and nissan is the only place i can seem to find the o2 sensors, and their askin $530 each! know any good websites to order cheaper ones from?
