I dont think it has a choke,it is fuel injected,,change coolant temp sensor it`s not exspensive,,then it could be throttle posision sensor or map /mass air flow sensor ,,,do check air filter before doing any thing and see if it is stopped up or really dirty

Automatic choke problems


Yes, spring may have broken or maybe it just needs adjustment. There is a high idle cam that makes the card idle higher when the choke is closed or partly closed.

Idling problem


it's supposed to do that as the choke is working to warm the vehicle, when it warms up to operating temperature the choke goes off

99 Chrysler Town and Country idles high


Maybe a sticking choke or binding throttle linkage. Have you lifted the aircleaner cover and looked down carb opening? Choke stuck?
Could be a simple idle speed adjustment also. What rpm's do consider to be high. Maybe some carb cleaner down the barrels and throttle linkage could free it up. Again, it could be a simple idle adjustment depending on RPM's it's turning.

Idles fast problem


That would be your engine "choke" functioning. It's not a problem. The choke engages when engine is cold and shoots extra fuel to the cylinders to idle the engine up especially in cold with. Once the engine has sufficiently warmed up, the engine will idle back down.

I have a 1990 nissan patrol. When i start the car te idle races off to 2300 RPM. The Auto choke seems to be free to move, and if i manually hold the auto choke off it stabalises at 1000 RPM


you can check for vacuum leaks use a short piece of hose like a stethoscope = no . try setting the choke.black and yellow part. loosen the screws and twist it counter clockwise, this should take it out of the high idle mode. the heater in the choke might be bad, ohm it and test for power

Carburetor idle mixture adjustment for lean burn chrysler engines


On a carbureted engine(the days of old) I had a method of my own
which always seemed to do really well.
Warm up the engine to operating temperature and make sure there is no
operation of the automatic choke.This should mean that the choke flap in the top of carb is standing vertically offering no resistance to airflow.
Hook up a tachometer if the car has'nt got one.
Note the idle speed in PARK.
Turn the fuel/air adjusting screw underneath carb's right or left sideI(NOT the idle speed set screw) IN and note the rpm as you do.If it raises a little,you are getting close.
Go ahead and turn that screw in all the way and lightly seat it(count the turns in from the highest idle reading),then back it out to the highest reading.NOW turn it in slowly until you see the RPM drop slightly.
Now back it out a little so you are at peak RPM again.
REPEAT this with the other side's fuel/air screw.
After you have gained this higher RPM (maybe), then set the idle speed control screw to desired RPM, and be sure to get in the car and while holding the brake,put the car in DRIVE to make sure the idle doesn't drop too low. don-ohio (:^)

1985 Nissan 720 ext. cab pickup problem


You need to adjust the automatic choke. Your choke may not be opening fully. There is a fast idle cam linked to the choke to keep the throttle open more until the engine is warm. The idle mixture screw is part 37 in the picture, but get the choke adjusted right first, and you may not have to adjust the mixture screw. See adjustment procedures at link beloe.

4runner idle high when cold after warm up it idle 1200 rpm shot down engine after fuw min. restarting the engine the idle to low?


it seems that the auto choke setting is maybe wrong or there is a problem with engine management, or a worn part which is sticking.

when cold, the engine should be higher as the choke will be on but a warm up idle of 1200 seem a bit high i would expect around 800 and then on restart if the engine is warm then the choke should be off but the idle being too low indicates one of the above.

When I start the engine from cold it runs on high revs too long


Hi ..... This sounds as if it's fitted with an automatic choke, as long as the revs drop when it's warm there is nothing to worry about. The indication when these start to go wrong is that the car won't start when cold ................ even then any decent mechanic can fit a normal/manual choke.

Excessive idle speed


The problem may also be the automatic choke. It could be stuck in fast idle. check all choke settings and linkages clean if nessesary. There is a separate fast idle adjustment screw on the choke linkage that controls engine speed while the engine is warming up. The tip of the screw rests against a cam that slowly rotates as the choke opens during engine warm up. Turn this screw counterclockwise to decrease the fast idle speed.
