found a bad connection at the harness side of the 02 sensor bank 1
that caused some jerking at about 2000-2500 rpms.gonna fix it later today
but was wondering has anyone had a no activity 02 code with drivability
issues?

I thought that the 133,134 and 153,154 codes were for the rear 02's and simply a cat converter test for emissions. That's why they can just be edited out or sims put in. I may be wrong but I had mine edited out after headers and hi-flow cats. The cats wont warm fast enough and it threw codes. No problems with drivability with or without codes.
