Are you able to hook up a scanner and watch real time data to see if you can identify which cylinder?
My wife had a CX9 that had a pretty severe misfire under load at low rpm, but no check engine light.
I bought a cheap OBDII reader and Torque Pro App.
I was able to monitor misfires and when it misfired, the counts went up on one particular cylinder.
That would at least direct you to which cylinder(s) is causing it.

The CX9 was a simple worn spark plug. I replaced it and car ran fine after that.
