Question about 2000 Nissan Sentra
You probably have a weak spark plug or injector.
You should get a check engine light and if you have the computer scanned you should have a code telling you which cylinder is not firing.
The problem is there at idle but not as serious as when you put a load on the engine.

The idle speed is computer controled, it is not adjustable, you most likely have sludge in the throttle valve and the idle speed control air bypass valve, clean them with carb spray with the engine running.

Check for vaccume leaks and also you PCV valve. check the hose too. Visually inspect every vaccume hose you can find. Sounds like a leak .

i had a similar problem a few months ago with my se-r. i went to the dealership and had them reprogram the ecm and it fixed it(its on the recall list for your car.) once i did that everything ran great.

I would pull the sparkplugs and examine.Are they Black? ,Wet?, Hot?, Cold? Also whenever you change the plugs change the wires (cap and rotor if app.).Cracked wires are hard to see but can cause spark to find ground before it gets to sparkplug.8 year old car how many full tune ups?.Good Luck.
