My 1994 GTi was doing the same thing. The car should idle a bit fast when cold, say 1500rpm, due to the auto-choke. However, 2800rpm is too high. I had a look at my throttle system and could not workout how to adjust the auto-choke idle speed seperate from the normal idle. So I reluctantly had it serviced by the agents, they cleaned out the throttle body and adjusted it. It is better, 1900rpm, but still a bit high for my liking.

There is a module called "idle limiter". Sounds as if it is bad!

SOURCE: Fully warmed up; blowing hot and cold; Suzuki XL-7

Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.

SOURCE: 2001 Suzuki XL-7. Heater blows hot one side, cold the other.

No ductwork [to the lower vents] under the dash. They are part of the heater core / blower housing is integrated (all one piece).

After reviewing shop manual, we suspect that one of the three damper flaps is not positioning correctly; or debris has blocked one side (which makes more sense given the symptoms).

We're waiting for the temperatures to get back in the plus numbers to check out the physical arrangement.

SOURCE: Recurring Mystery Problem in a 1986 Suzuki Alto. (Idle related)

Bad fuel, water in the fuel, dirt in the fuel.

Drain the fuel tank completely.

Pour in a gallon or two of fresh fuel.

See how it goes.

Put some of the old fuel in a glass bottle, hold it up in front of a light and see if you can see any foreign material in it...

I have a 1986 glowing 1200a it cranks up run smooth still it warms up it will idle cold and when it gets warm up to around 2800 rpms the choke cable is broke be the problem if it stuck closed some


Yes indeed the choke being closed even a little will cause this. Replace the choke cable and stop your problem. After warm up the choke should always be fully open.

Another thing that can cause this is the carb. It may be getting too much fuel once it's warmed up. An engine needs more fuel when it's cold than it does when it's warm. Cold engines run inefficiently so they need more raw fuel to fire-up, and stay running. This is all a choke does. A choke plate closes-off the air going into the carb which makes the fuel mixture really rich so it can run. Less air = more fuel. You'll also notice that cars with chokes also idle real high until they warm-up. This fast idle and the over rich mixture (due to lack of air), allows the engine to fire up and stay running. As the engine warms-up and starts burning fuel more efficiently, the choke plate begins to open, which slowly lets more air in and leans-out the air/fuel mixture. Once the engine is warmed-up, the choke plate will be wide open allowing the carb to run as it is supposed to with the correct metering of fuel and air.

I have a 1986 GMC 1500 with a 5.0 and stock rochester carb. The truck will start but you must keep gassing it as it won't idle. It kicks off every time. Any suggestions on how to fix this cold natured


fast idle speed screw, works off the fast idle cam which the choke adjustment sets, it works together by linkages. This is the raised idle speed setting you need to keep a cold engine running. First you set the idle speed by the idle speed screw with engine at normal operating temperature. Then you set the linkage up so the cam is on a raised step, throttle will be held on that raised step. then you can turn the idle speed screw to get idle at about 1500-1800 rpm. Now when you start engine cold, choke will set the fast idle cam on that raised step- when engine starts and runs it should be running at your fast idle setting. That's how it supposed to work, you just have to get everything adjusted right. I hate carburetors, they never stay adjusted right. Considering their complexity and small mechanical parts, no wonder.

My 2.0 engine idles fast on a cold start. Then idles down after warming up.


This is normally the way it is suppose to work. You need to have the RPM measured for High RPM and duration. What you are describing is how an electronic choke is suppose to work.

The errors would be how high the RPM goes and for how long it lasts. When cold the RPM, fuel mix and timing are changed to give a rich fuel mix. As the O2 sensors warm(Could be defective) they signal the engine to lean up. The water thermostat also has something to do changing the engine to a lean running slow condition.

If obtaining heat from your heater seems to take Forever, the thermostat could be weak. This would coincide with the engine continuing at a high RPM longer because it is not warming up.

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.

1986 misan 300z car will ot idle when first starts


Check that the choke is not stuck open or not working at all. THe chole has an accelerated idle cam which increases the idle speed when the engine is cold and the choke is supposed to be closed and as it starts to open.

Engine idles excesivly high after carb was rebuilt.


You need a new choke pull off. They are around $30 dollars.

89 dodge shadow. hard start. normal idle cold, fast idle warm. sometimes it wont start until i hear fuel pump activate.


Hello,
The car may be hard to start because it may need a normal tune-up. If the spark plugs are pretty used, they will slowly stop burning as much fuel because the spark slowly gets lesser and lesser. On a cold day the fuel is harder to ignite with a small amount of spark.
Normal idle when its cold means that your cars idle is probably too high. If you lower the idle, the choke on a cold day will keep the idle a little higher until the motor warms and then it will kick back off. If the idle is too high, it will run very rich, smothering itself with fuel, and causing the idle to stay low. When the car warms, its creating better spark when its warm, and with the idle being too high its running at a fast idle.
The car wont start sometimes can be the cause of a few things. If the ground is bad on the fuel pump, it wont make a good connection sometimes for when you turn the key on, the fuel pump dont pump the fuel to the engine. Another one can be that your accessory switch can be loose going to the fuel pump. I think its your ground though. Good luck! Hope this helps.
Have a nice day. -Steve

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.

that is totally normal, the car has an automatic choke that makes is rev at those RPMs when it is cold then is goes back to normal when it warms up. don't worry about it!
