Truck is a 4WD, V8 7.4L 454 CID Gas. I had a tune up done and there was a computer error code P0137. Tech said it was an Bank 1 Sensor 2 Oxygen sensor failure but the "Check Engine" light has never come on. The truck is a 1997 and has only 113,00 miles on it. Should I replace that sensor, and if so, where is it located? Before the tune up the truck was running and idling very rough and would shake. Gas mileage was really bad.

Sometimes when the car slows to a stop, the car dies. Idle set at 900 rpm. Car starts back right away.
