96 5.8 Fault code

My 96 has been showing an 02 sensor code for several months I've replaced all 3 sensors and have verified that all the wiring is in good shape.It's been diagnosed by 3 different shops and all say it must be a bad ECM.It comes down to the ECM being bad.Does this sound reasonable?This truck only has 80,000 miles on it and runs perfectly,but is using a lot more gas than it used to.

I would have to say it’s OBD-II.
