Bosch 13111??s
Bosch 13111??s Ok i put a set of hedman long tubes on awhile ago and of course ive been throwing all sorts of O2 codes. Right now im throwing P0133B(slow response b1 s1) P0420A (system low effic. b1 s1) P1153B (circuit insuff activity b2 s1) P1133B (circuit insuff activity b1 s1). So my question is, if i replace both my front o2s with bosch 13111s will this solve my problems?? Will it fix them for good or will my headers burn them out quickly as well. My stock O2s are hooked up.

and I don't think it's your headers burning the sensors up per se. It's just the stock sensors in the long tube can't maintain the temperature they want to maintain as the airflow across the sensor is greater
you might try to find a store that will take back the sensors if they don't work...tell them they didn't fit or something
buy the sensors and see if you are still throwing the same codes/having the same issues. if you are, return 'em 
Im not tuned yet. I was going to try to get her tuned this winter. Does anyone know where i can get a tune in Nebraska?? I tried to search for one but had no luck. So should i leave the o2s alone untill i get a tune??

The 131111's worked for me. The good thing is they have a longer pigtail so you don’t have to splice or buy extensions. When I put my headers on a year ago I put a set of new stock bosh O2's in there and they lasted about two weeks. The 131111's have held up great and seem to switch a little better according to the logs that I have done.
