How long does a warm engine idle for?
With a steady throttle, it fluctuated between 3 and 3.5 for a couple mins, then bogged out and stalled. Next time I started it, it went to 2k intially then started hunting between 1k and 1500, with about a two sec interval. After a couple mins, fluctuated around 750, but not steady.

Can a low oil level cause a car to shut off?
Can low oil cause a car to shut off? Low engine oil level does usually not cause your car to shut off. However, if it is too low so your oil pressure is getting low – the car can shut off the engine for safety reasons. This is often in newer cars, though.

Why does my car keep cutting off when I stop?
Why does my car keep cutting off when I stop? If your car shuts off after you stop it is because the engine is very sensitive at idle. This can be caused by many things but is usually caused by a lean fuel mixture, causing the idle to drop too low.

What happens to the warm engine when the battery is disconnected?
Warm engine idles rough and stalls. Runs fine when cold The majority of idle issues occurring after battery disconnection can be resolved with a throttle cleaning. When the battery is disconnected the computer loses it’s adaptation for the idle air bypass and the idle air control valve resets to it’s default position.
How does a warm engine work when cold?
Runs fine when cold Warm engine idles rough and stalls. Runs fine when cold The majority of idle issues occurring after battery disconnection can be resolved with a throttle cleaning. When the battery is disconnected the computer loses it’s adaptation for the idle air bypass and the idle air control valve resets to it’s default position.
What causes an engine to stall at idle?
If the ISC valve is gummed up with fuel varnish or dirt, it may stick, preventing the engine from maintaining the proper idle speed when the throttle closes. A faulty idle speed control circuit may also allow the engine to stall when idling if it fails to compensate for idle loads placed on the engine by the charging system or A/C compressor.
What does it mean when your engine idle does not increase?
Use the command in the scan tool to increase the engine’s idle. If the engine idle does not increase, it means there is an issue at the idle control motor of its circuit preventing the signal from changing the idle. You can purchase a bidirectional scan tool at your local auto parts store.
What makes a car stall when the engine is warmed up?
The rpm’s will drop to 500-800, engine will shake, and either stall out or surge up to 1300 rpm’s before going back down to 1000. When the rpm’s are low if I press the gas nothing happens or the car stalls out immediately. This only happens once it is warmed up.
How can I tell if my idle control valve is working?
To check if an idle control valve is working properly, start by turning on your engine and letting it run for a minute or 2. Then, when it’s at an idling speed, take note of the RPMs in your car. Next, turn the engine off and disconnect the idle control motor under your hood.
What causes a car to stall at idle?

Why does my C3 Vette die at idle?
In Park with the engine running at idle, after it fully warms up, the engine starts having an erratic idle then eventually dies. Then it won’t start until the temp of the engine drops down a bit. So my guess is this is definitely not a vacuum leak, it’s just got to be something with the carb.

The car is undriveable when warm.
What makes an engine run and idle without stalling?
Every engine needs three things to run and idle smoothly without stalling: a correct air/fuel ratio, sufficient idle speed for the idle load, and a good spark. If any of these is lacking, the engine may stall. Cold stalling problems are the most common because the engine needs a richer fuel mixture to maintain idle speed until it warms up.
Why does my motorcycle engine stall when warm?
And the problem is often worse on a hot day. The dreaded stalling issue when the engine is warm is the most common idle problem and it is mostly related to the very lean air/fuel ratio on the modern fuel injected motorcycle engine. Why does my motorcycle stall at idle when the engine is warmed up and at operating temperature ? – Low compression.
What are the symptoms of an engine stall?

When does the idle air control valve stall?
However, when the engine RPM drops below the normal range of 800 RPM (for most cars), it is more than likely that you are dealing with an IAC valve problem. In cases where this valve is clogged or is nearing its replacement age, your vehicle will stall instead of idling after the release of the throttle.
Why does my car idle at 700 rpm?
There is an air filter which prevents debris from the air from getting into the chamber. But if this air filter is dirty or clogged, then there will be less clean air passing through it. This will cause the engine to idle rough. Your engine should normally get to around 700 RPM after you start the vehicle.
What happens when IAC is stuck at idle?
An obstructed or stuck-shut IAC will result in a rich air-fuel ratio at idle, so the engine will start very easily while cold and then die suddenly after a slight puff of black tail-pipe smoke. A stuck-open IAC might start fine while warm and may continue to run if the engine reaches high-enough RPM.
