My buddy had that problem with a couple of o2 sensors and the auto store said it must have been a bad batch of sensors

3 in a row were bad right out of the box. Id put them on the truck, go a few miles, and light come right back on. 4th one finally worked correctly!! I think thats pathetic!

Mine runs great, it just gets worse gas mpgs..i think its the heated part of the sensor thats bad

They didnt always just immediately throw a code, but always had bad gas mileage till I finally got a good one
