New O2 sensor? Is this what they look like?

[Johnmadd]

Already did. Surprisingly great customer service from Oreilly's around here. The store only had one in stock which is the one I ended up with. Called them, told them my concerns, and they have another O2 sensors being loaded onto a truck shortly. I will be doing a direct swap in-store in a few hours. Losing a few hours is all, not to bad considering. Luckily O2 sensors are real easy to swap.

Good to hear, could have gone totally opposite.
