i actually had this problem on my 97 sentra, its the air idle control valve. when your car is idling with your foot off the pedal, the throttle plate is closed, so this little valve opens up to allow air to detour around the closed throttle plate so your car can continue to run, when you give it gas the plate opens so your engine can increase revs.
after awhile the idle air control valve gets dirty with carbon buildup and eventually makes the valve stick so no air can pass through it which is why the car will stall when it attempts to idle. all it needs is a good clean. its very easy to do, just get some brake cleaner and a toothpick or q-tip or some other small brush.
locating this valve is a bit tricky, yours is a 2000 model mines a 97 so it wont be in the same location as mine, but what your looking for is a little cylinder type thing somewhere near the intake with an electrical connector at the back of it, take the connector off, mine had 2 phillips head screws holding the valve in place, once removed the valve slides out, and you can proceed to clean it. make sure you get all the black soot out of it and play around with it until it opens smooth, reinstall and it should run fine. to find out the exact location of your idle air control valve id google it or try a nissan forum, but itll be close to your intake manifold near the firewall. best of luck, once found its a very easy fix.

Engine stall or RPM fluctuates
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
