o2 sensors??
o2 sensors?? i replaced plugs and both front o2 sensors rears are deleted but i'm still throwing a code (B1S1,B2S1)after about 100 miles?car runs really rich on startup skips then clears up but dumps fuel smoke out the back, anyone have this problem? mods in sig.

What are the exact codes
B1S1 is driver front, but B1S2 is post cat driver side ... there are a bunch of codes that mean different things for each sensor... so need the P0xxx codes
who did your tuning? No one should ever delete your front O2s unless you're using open loop speed density 100% of the time

sorry my mistake it was B1S1 and B2S1 got them mixed up the rear o2s are deleted and i never had problem till i put headers on it and the high flow cats.
