Update. I took it to a local Ford dealer who replaced the #3 EGT sensor. O'Riley auto parts said it was the #4 sensor, but . . . They also said it didn't need a Manual Regen which I find hard to believe because I don't believe it's done one for some time given I haven't had to add and blue-def for 3 or 4 months. They also did a chip software update which is supposed to help with the mileage. However, I drove it home, about 6 miles, didn't drive it for 3 days, and when I got in it this morning the engine light was back on. So, back to Ford I'll be going. I will ask them about MAF Sensor, thanks for the suggestion. The saga continues. Again I very much appreciate all the great feedback!!!
