And... the story continues.
Took to shop, supposed to be best shop in city. Replace differential sensor. A week later, started car, reving up and down and stalls within 10 seconds. Towed to shop, replaced mass air flow sensor but lin bus still failing. Shop said PCM recently replaced by dealership likely culprit. Now have to tow it back to dealership.
So far, approximately $2k spent and as of now, car can't move, which is worse than what it was before I took it in for repair.
Never touching a Dodge again.
