Question about Nissan Cars & Trucks
I always use a lot of fuel idling my car before it warms up should it not have a choke
If it had a manual choke you would see it on the dash board , i'd get the engine tuned as a vehicle of that age could well have an auto choke mechanism so may need attention to that

SOURCE: Carburator and idle problem
Believe it or not you just said the solution to your own problem manufacturers specs requires for any adjustments to engine idle or other carburator adjustments to be preformed while the engine is idling and at normal operating temp in plain english let the car warm up then make your idle and mixture adjustments if this doesnt solve it i would check the auto choke and make sure it is opening at normal operating temp hope this helps good luck

SOURCE: idling high
are you using aircon? if yes observe if it beahaves OK if the aircon is OFF. Then if you turn the aircon ON does it go up? if so, you may have no freon on the system because the engine does not have a load and the aircon system is idle upping your engine.

Although this isn"t a proper fix, and may affect emissions, I ran accross this problem on a friend's 87 2wd wagon.
There is a dashpot that controls a lever the Idle set screw is on, I am guessing it is a decel valve that closes butterfly when coasting in gear. I never looked at a manual to figure out what controls the vacuum valve that is on the passenger side of the engine compartment, but if you disconect the vacuum line and plug it that lever will not back off and idle will remain where you set it with the adjustment screw.
Make sure the engine is warmed up and not on a fast idle cam before adjusting idle.
The car is a 5 speed, I not sure if automatic cars are the same.
The car idles fine now and still run's great and gets 37+ MPG with 240000 miles!
If you want to fix it properly you would have to diagnose why that dashpot is being actuated at idle
