I need to buy a new single wire O2 sensor for my 90 civic with B16a sir. I have tried two old ones and neither one sends my afr meter past the first light. And I know I can't tune with a non wideband, I just like the lights.

If your not throwing a code, then don't worry about it, your o2 sensors are fine, and if you want an accurate a/f ratio, then get a wideband.
