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.
Mine just doing this all well, no codes came up, still have not found out what it is
i am currently working on this model with the same problem, i will be checking for vac. leaks,collapsed lines and bad gaskets then the idel controller i will keep you posted once i find the problem
