It was first a fuel sensor &/or an oxygen sensor or both. I had the same issue twice within a few weeks of repairs. They saw white stuff on the sensor & sent it to corporate headquarters. The fuel was being flooded too much for the settings. They had to reset everything twice. So far so good, but it was a weird situation for a while, especially since no one had a clue why this happened.
Update from Nov 30, 2019: Oh, the fuel mileage was down to 12 miles a gallon when this problem was occurring, but that is not saying much - since I only average around 16-18 miles a gallon.
