Potentially unrelated, the vehicle has been idling noticeably rough and at times the RPMs fluctuate ~200-400 especially when it’s hot out.
I have an appointment at a local Toyota shop next week but wanted to see if the interwebs had any insight.

If the engine was burning coolant, you would smell it. Also the level would be going down.
