Engine Problems

Hey ppl. I have an '85 Rx-7 with the 12a engine. I am having some issues and I was hoping someone could help me out. The problem is when I start the car I have the choke pulled. It starts fine but once the choke lets go it idles extremely rough. Also it stalls once under load. I unfortunately have an A/T. Al the usual suspects appear to be fine but I am unable to pinpoint the culprit. As I said before any help would be greatly appreciated.
