These are the sensors my engine analyzer said I need to replace. I am assuming they are located underneath the truck on the converters. But I'm not sure. I think it is a 4.6. Thanks Ken

So changes of both oxygen sensors being bad is remote.

P2197: O2 Sensor Signal Stuck Lean - Bank 2 Sensor 1

P2195: O2 Sensor Signal Stuck Lean - Bank 1 Sensor 1

These are stuck lean due to a vacuum leak or a bad MAF sensor.

Here is a guide to you understand what's going on:
