If the Ses light cleared than yes. Do you get new codes and if so which and do you hear knocking before codes trip?

If you have oil filled to mid way I would drain half a quart or so to add 1 qt of Lucas oil treatment then if you don’t hear knocking like actual bearing failure it might be a coincidence like low fuel pressure causing your multiple cylinder misfire.

If the bearings are toast either crank or rod, I am pretty sure you’ll be hearing them complain to high heaven.

Does your Carley app allow real-time view of horsepower? Or: can you connect to the Carly WiFi dongle with a different app. A couple apps I use will calculate real-time Hp and if it for example takes 9hp at idle and shoukd be 6, it’s solid evidence that oil is not getting where it should.

If the bearings aren’t shot but oil got cooked into goo in some small passageway, you may be able to use some engine flush (basically kerosene) to cleanse out the gunk

Stay positive for the moment; I’ve had seeming worse things turn out to be a dirty connector.
