P0154 I am getting this code. I swapped the o2s to see if code would switch to drivers side being bad. Still the same. What are the next troubleshooting options. Both the 02s are damn near brand new.
could be bad cats if the o2s are working rt,or if u have headers and are using just the front u may have to switch to the vette ones they get hotter which is needed since they were moved further down on headers.
