I never did that with my automatic Ford Escort, but over the years I have heard a few people with manual tranny cars mention they decelerate in neutral, instead of actually shifting down the gears as the speed goes down. I'm not much for driving my cars in neutral.. only at stops do I use neutral sometimes.

Thanks MetroMPG! I read the entire thread and it was helpful. Though, I want to be clear about what I am experiencing.
Sometimes, when *Almost* coming to a complete stop, like 3 mph... 2 mph... the car with lurch as if it is doing an abrupt 2 to 1 downshift or 1 to neutral shift. It doesn't happen all the time and I can not find a way to make it happen intentionally. My best guess is that it is the "Idle Neutral Logic" and it's just trying its best to do what it thinks it should do and once in awhile it gets it wrong.
I'm not worried about the Idle Neutral Logic as much now. I appreciate everyone's comments on this.
Also, from the thread on Idle Neutral Logic (https://mirageforum.com/forum/showth...ll=1#post58905) post #19 by beacon
"Edit: after some more research, it IS a Jatco cvt (Nissan) which features a lock-up torque converter, and it's rated for double the horsepower of the 3A92 engine..."
So, for my other issue, the one where I feel like the car is struggling, herky-jerky, or slipping a little under light acceleration while cold, I double it's causing any issues. The itty bitty 75 hp engine most likely won't be able to damage the CVT belt/pulley anyways. Plus, again, I drive like a grandpa... especially when it's warming up.
I don’t know about the safety aspect of coasting in neutral to a stop but I can tell you it is most likely more fuel efficient to leave it in drive and coast or brake to a complete stop. While the car is in motion, in gear, and has no throttle input the fuel injectors should stop pulsing. While in neutral the fuel injectors still need to pulse or the engine would stall. Same principle if you are coasting in neutral or stopped/parked and idling... injectors must pulse.

The idle neutral logic saves gas while idling because it reduces engine load with respect to the transaxle being in gear at a stop.

Its also caused my 2014 DE CVT to slide back and almost hit a car in a drive thru. I was sitting for about 2 mins with my foot on the brake and before I could hit the gas it slide back about a foot. Maybe something is wrong with my hill start assist?
Hill start assist wont work unless you do a full stop when on an incline.
