What should the idling speed be on a new car?
What you want to do is find out where the car should be idling when it is completely warmed up. These days the normal range tends to be anywhere between about 650-900 rpm. 1000 is on the high side, and 1700 is certainly on the high side for cold start up.
Why does my car idle higher at start up?
So if there is a problem it isn’t that car idles higher at start up – its supposed to. Its that it is idling a little high to begin with, both at start up and after warming up. A small vacuum leak can cause that as can a sticking or malfunctioning idle air control valve.
Why does my Ford Mustang idle at 800 rpm?
The car had underdrives on the crank and waterpump before I bought it and the volt gauge does not go up until about 1000 rpm. Even with this the car would idle before at 800 rpm. When I added the parts in the sig, the engine would not idle at all. The car died every time it came to a stop.
What is an example of a high idle?
Example: You pull up in the driveway or to a stop light with the clutch in and the car idles it self up to 2K or 3K rpms and then stays there, then finaly drops down when it wants to. Or, your driving down the road, push the clutch in, and the car stays at whatever rpm you were at when you went to make the shift for more than a sec or two.

What’s the idle speed of a car in winter?
Whether winter or summer, when you first start the car after sitting overnight, the idle immediately races to 2,000 rpm, then drops to 1,800 rpm. It will then idle at 1,800 rpm for another whole minute or so, and then slowly start to drop off to 1,600 etc until it reaches about 1,300 rpm after about two full minutes.
Why does idle speed drop during cold startup?
If the idle air control valve did not compensate for these, the idle speed would drop when certain accessories are used. In severe cases, the engine may even stall. The idle air control valve is most important on a cold startup. Problems with the idle air control will be most obvious during this time.

How can I tell if my car is idling?
When you start your engine, and just let it run without pressing on the accelerator or putting it into gear, that’s idling. A properly idling engine should be able to maintain a steady but low rate of revolutions, somewhere in the vicinity of 1,000 RPM. Your tachometer needle should be steady and not jumping around.
What can cause a car to die while idling?
Defective auto transmission can cause this problem. If the car dies while idling but restarts later, drive the car up and down a steep road to see if the problem persists. If the car still stalls, it is certain that the source of the problem is a blocked fuel filter. You can easily replace it though and it is pretty cheap too.
