After i start the ignition my RPM goes a little above 3 Of Coure to warm up/ready for the day...Then my rpm start going under 1[which is normal about 1 or 2mm down]...then my cars about to die keep going to "0"~!! i could hear the engine dying..revving..then going all the way to "0" rpm..once in a while it died on me so i had to revv my rpm with acceleration to keep my car going..whats the problem??

 

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...
