O2 sensors bad? irratic a/f readings.

OKay I just installed longtubes (NON coated) The way that the o2s were drilled run into the bellhousing. I had them redrilled when I got my Ypipe made but havent moved them since they are so close that the header needs to be off to get them out (probably pinched the wires)

ANYWAY

I was driving around tonite and I got on the car hard and the wideband went MAX LEAN so I got off and it stayed lean the rest of the way to the movies. I leave the movies and it was lean the rich then lean etc.

While driving at a contant speed the wideband jumps from 12.0-MAX lean then around 14.5 then rich then lean etc. Basically it is all over the place.

Im gonna drive the car into work in the morning and log my drive with tuner cat and see whats up.

Does it sound like an O2 issue?
