OT: Having your car sitting for a few days ?

Miami, FL (or the nearest big-booty club)
Had not started my jalopi for 4 days - decided to start it today and it was sputtering - I let it idle on its own for a while and it kept sputtering - I then starting revving it some while parked and it kept sputtering but after continuing to rev it it eventually started idling smoothly although I didn't drive it and just let it idle for about 5-minutes once it started idling smoothly.
Anyone know what may have been behind the engine sputtering like that (I haven't driven it yet, will probably drive it tomorrow).

Carbureted or fuel injected? What kind of fuel injection, how old? Some kinds of fuel injection had serious vapor locking problem, if jet seals don't close right. Newer kinds usually not like this.
Look for water or oil loss. And always look for ATF getting into the water too.
How old spark plugs, miles?
Either check spark plugs or just buy new ones. But always check old ones for problems. Spark plug checks are an important diagnostic.

Usually if a car sits, all that happens is the battery goes dead.
But what you are describing sounds like vapor locking, or water or oil getting into combustion chambers, or just thrashed spark plug electrodes.
How many miles on car, on spark plugs, on ignition parts, water or oil loss, fuel injected or carburetor?
Oh, I see now, 2015 Nissan, sequential fuel injection. Those very unlikely to vapor lock, as injectors just go straight up to fuel header.
Has low pressure shut off valve to stop fuel from getting out of header when not running. But that could fail.
Probably problem can be found by watching for oil or water loss, and by looking at spark plugs. 50k miles is not a lot, but things do fail. Ways for oil or water to be getting in. This will show if you check spark plugs.
Fuel injector cleaner in tank might help injectors close better. Another good first thing to try.
Any other incidents like this?
Remember, fuel injected like that, they circulate the fuel, up to the header, then back into the tank. Pump has great surplus capacity when running at low power.

Come on man! 2 Sentences for a car problem? Should have been a page or two! :)
Meat, you could always send him some dry Arizona air. :D
It's a jalopy if it's an Infiniti.
