Well we never got the problem solved, but they tested everything they could over a two period. The service engine light is on but does go off for a time after it recycles a number of times. The truck runs fine with the service engine soon light on. I came back and got a full oil change And filter, but it did not fix it either. I feel everyone did the best they could.
Thank you for your honest feedback, Lonnie. Please don't hesitate to reach out if there's anything additional we can do for you.
