Just recently I have begun to have the problem where most of the time when I drop below 1000 rpms my car stalls. Sometimes it stutters and then dies or I can rev the engine to keep it from dieing but for the most part it just stalls out and I have to wait until I stop and it will start right back up again. I have even had it happen while going at speed and I then need to stop the car and start it again. If I keep the rpms above 1500 I can usually keep it going. This usually happens when I am slowing down to stop or make a corner.
Stalls when I go below 1000 rpms. on 1996 Nissan Altima

Sounds like your Idle Air Control Motor should be inspected. This is where I would begin. And you also may have a sticking open EGR valve. Check for any Check Engine Light codes, and be sure to resolve those, because they will help you Diagnose this problem.
