You might try this:

Turn the ignition switch on for 10 seconds and off for 10 seconds. Do not start the engine. Repeat a total of 4 times.

Make sure the intake bolts are all snug. Might be a slight leak somewhere.

Maybe the parade mode got turned on. This turns off the rear cylinder to provide cooling in hot weather while idling. Check the manual how to turn that off.

25 Heritage 285 miles - not seen that symptom yet but thanks for the heads up. Been on the charger here on and off for a month as weather tuff here.

Ride Safe 🤙 James

My ‘23 also suffers a wandering and occasionally rough idle. I’m coming to suspect it’s related to my battery.

The battery doesn’t hold a charge well, and can struggle a bit cranking the engine over. The engine will also run roughish.

Hook up a charger and let it sit for a bit, and the engine spins over briskly, and idles smoothly.

EITMS seems to be the issue.

It is enabled from the factory. So, by “issue” do you mean you want it disabled, but you don’t know the procedure to disable it? If so, the procedure is in your owner’s manual. In the manual index, look for EITMS.
