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.

SOURCE: 1984 Toyota tercel wagon

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

I have a 1984 Nissan/datsun 4X4. Will not Idle properly, just dies if not constantly given gas. Sometimes has problem starting. Any ideas?

The throttle/choke adjustment would correct this. If adjusting this does not make a difference then the carb will need to be rebuilt/replaced.

1984 passat cl. the automatic choke runs too fast

the choke has 3 screws to adjust the unit,the choke itself will normaly be siezed inside at the age.With a warm engine, loosen the 3 screws and turn the choke untill the idle drops.

or as i did it-with a cold engine, remove the airffilter and with the 3 screws loose on the choke press the accelerator pedal just over half so the choke is engaged and the looking inside the filter housing adjust the choke flap by turning the choke housing until the flap is 3/4 closed and tighten slightly and start the car.Do remember to check your distributor timing whith a warm engine and make sure the sparkplugs and airfilter are okay as each upsets the other.

The carburetor of my nissan adresort 1996 model is fickle

That might mean the lower butterfly isn't opening as the engine warms up. The hotter it gets, the more air the carb needs. It isn't getting it would be my first guess. Or he has it running too lean to begin with from the fuel mix adjusters. Add heat and it starts choking. It might not be your carb. You could have a dirty tank, lines, fuel filter, maybe fuel pump (I doubt it though) No offense but a lot of mechanics are good toolsmen but bad diagnosticians.

84 Nissan Stanza, engine chokes during idling mostly

At first i was thinking about electronics and such, finally stopped to think a bit and figured i was dumb not to notice it was a 1984 and in that year there wasn't much electronics involved. And usually when you get that kind of problem in a car from those years, it's due to the old school carburetor. Either the small filter hidden inside it is deteriorated and clogs the passages preventing the fuel exiting from the jets or the floats inside it are done fore and need to be changed or the carb needs to be retuned. With something that old it could also just be that the gaskets are to old and started leaking air into the fuel, causing bubbles in the fuel lines. I would recommend getting it check, but not at the local garage, find an old school mechanic that used to build hot rods back in the days, those old timers sure know how to fix and tune a carburetor to get the max out of it.:) I owe most of my knowledge to old timers like them.:)

Problems with idleing with a manual choke

Check the flexible pipe wich extends from the exhaust manifold to the bottom of the air cleaner inlet. if it is missing or not properly mounted you will have that exact concern. If it is there and looks functionable have the carburetor rebuilt by a professional. The primary fuel circuits are clogging/varnishing up and the passage becomes smaller not allowing fuel to flow properly. The engine can handle the lack of fuel better when warm. At the time of rebuilding they must check for cracked vucuum lines and check the linkage for the choke and fast idle cam. This will ensure proper fuel delivery and cold engine enrichment as needed. Good luck
