If you can’t diagnose it yourself, take the car to a competent dealer or independent repair shop where they can look at it.

Isn't it odd that a misfire isn't causing a code to be stored?

Then maybe it isn't a misfire.

Could be something slipping in the transmission? Tire slip?

Hook it up to a data logger and have an expert look at the results?

You need to have someone scan it with a tool that can count misfires and the cylinder that its happening on
