so i just got my car a little while back and i am pretty new to rotary engines but the problem i am having is the car starts up fine and it sits at 1500 rpm till it's warm but once it gets warm my idle goes down to the right rpm range but after a little the rpm will trail off till the car dies unless i keep my foot on the gas and hold it their. another problem that i am pretty sure is related to this one is that the idle screw doesn't do anything and the car is running really rich which i am not sure is related.
