A rough idle

could be the air sensor. rotary cars need to be warm before you drive. rotaries run high rpm when you start them to make the car warm. id recommend letting it warm up for like 5 minutes before you drive and it should be good to go. if not check the bypass air sensor.

Definitely needs warmed up. I believe that's why Mazda engineered the ECU to run the car at something like 2500 RPM for a couple minutes on startup (stock ECU, not positive which model years). I usually let my water temp hit about 60 deg Celcius before expecting it to perform as desired. At that point the tach needle is as still as can be at idle.
If you don't have a digital water temp meter, I would imagine that 60 deg C would probably be just shy of halfway up the stock meter.

The high-rev is just the cold start system. It should be warmed up at idle for 2 -5 minutes before driving to reach operating temperature/ wait for the thermostat to open.
If you're worried I'd check all the fluids, test for spark and compression to put your mind at ease.
