I have a 97 ram 5.9 that runs roughy and stalls in park but runs smooth and doesn’t stall in reverse neutral or drive. As soon as I shift it back to park it smells like it is loading up and dies. It won’t start in park without starting fluid or gas in the throttle body but in neutral it will start right up. I have changed the crank sensor and map sensor and computer. It will throw a P1391 code if I keep it in park and press the accelerator to keep it running. I clear the code and leave it in neutral drive or reverse and it runs smooth and doesn’t set the code. What can I try next?
