Interestingly enough I've had the misfire and vehicle rough idle with it in park sitting at a scrap yard while I was taking stuff out of the bed. It was running fine and then I could feel the bed bouncing around. When I finally got back in the truck my wife mentioned that something strange happened and she felt the bouncing as well. What was the disconnect between the transmission software and throttle body after sitting idle for about 3 minutes? But I'd guess some of us have different issues that just present themselves in the same way (e.g. CEL and ESS lights)The interstate misfire I am pretty sure is a bad integration between the transmission software and throttle body air flow model. Which puts the engine in a bad spot on the timing map. I have a file that makes it happen almost on command. Changing the timing gets rid of the misfire code, occasionally the Avengers logo pops up. I believe the ESS gets angry when the the throttle body osscilates and the lockup clutch slides in and out. I have noticed on the 2020 rams they have really pulled back on the throttle closed loop control and limit the amount of correction it is able to do. I imagine that is why many feel the throttle is lazy off the line in those trucks. For the record I don't think any harm will come from the interstate misfire code. It is not really a misfire. It may eventually be hard on the torque converter. The actually engine misfire is due to the engine controller racking the cams to the min setting and limiting throttle body opening, after the code is set. If you have a Tazer, you can just clear it and be on your way.
