Half of the stuff on the motor is to control emissions, and the other half is to control idle speed.
The rotary engine makes a lot of power for it's size, but low end torque falls way off, so idle speed control is tricky.
There is an idle speed adjusting procedure in the "fuel & emissions" section of the manual.
There is a link in my sig.
Download & print what you need.

Start with a through inspection for any small intake vacuum leaks.

What might need adjustment on your motor:
Throttle stop screw adjustment
cold start fast idle cam throttle screw adjustment
BAC clean & test

Has the engine seen a tune-up recently?

Else, intake vacuum leak...
