Well apparently Amazon agrees with Ford. Thank you - that is absolutely informative.
I figgered EVERYBODY knows the sides of the banks after 80 years of seeing them longitudinally.Since the 5g explorer uses a transverse mounted engine, there isn't really a driver or passenger side to the engine. You may want to explain it in terms of engine orientation (from front or rear of engine) as I am sure someone is bound to get confused.
On explorer, bank 1 is near firewall and bank 2 is near radiator.
As for the op, you shouldn't be paying $300 for an O2 sensor. They are $35-70 from rockauto. Depending on your mileage, you may want to change all of them. You can swap them around, to see if you can isolate the problem, just be careful that you don't damage them when doing so. Once you factor in the time to do that and retest, you may find it easier to just replace them.
