Hi,did you bleed the cooling system? Not sure but a few Nissans have a system to monitor the engine temperature to release the choke.Did you remove a couple of small coolant hoses?If you did you may have to 'burp' the cooling system.

JUST REPLACED CARB ON MY 1992 CHEVY SILVERADO WITH A 4.3 LITER. NOW IT STARTS AND RUNS FINE UNTIL IT WARMS UP THEN DIES AND WONT START FOR 30 MIN


How many rpm's is it running at when you first start it up and it is running on the choke? Does it gradually start to idle back and then start to die r does it do it all of a sudden and dies?

When running with the choke on, it is on the high idle circuit of the carb, as it warms up the idle should slow down and then idle in the 800 rpm range in Park, 650 in Drive. This will be the low idle circuit range. This transition inside the carb will cover an idle air bleed hole in the venturi of the carb and lean out the mixture. If you notice that the carb smells gassy and black rich unburnt gases are coming from the tailpipe, the problem is located within the carb and requires a carb tech to do a rebuild of the carb. You could try a good carb cleaner like Lucas by putting it into the gas tank, in case you just got a bad tank of gas, but that is just a bandaid for a more deeply rooted problem. Get the carb rebuilt?

I would check the ignition module then maybe the coil. Check with autozone or kragen they should test it for free.

Idle


i strongly suspect a vacuum leak.. check for disconnected hoses or intake area leaking by spraying carb cleaner around those areas while idling.. if engine personality changes you are close

Check your Ignition timing before anything
check your plugs see what color they are
red or orange means carb is to lean , black
or oil means to rich then you can go from there
and set mixture screws on carb , let me no how you make out .

1987 Nissan Sentra Wont Start (died after going through a puddle)


the EGR (exhaust gas recirculation) valves like to stick on these cars, they get fouled up with carbon and if they get stuck open, the car will not want to idle well and even stall out. they are vacumn operated and can usually be cleaned with some carb cleaner and small picks. before you clean it, try moving the diaphram up with your fingers and see if it comes back down. this will tell you if its stuck. the EGR manifold port can also become clogged solid and requires removal for cleaning.

Idle flatutes


The throttle valve and idle speed control valve may be sludged up, clean them and retest the problem. Buy a can of spray carb cleaner, spray it through the intake until about half the can is used up with the engine running, you will need to hold the idle up or engine will die, disconnect the battery for 5 minutes then reconnect.
