What happened to Buick gl8 idling flameout (how to adjust the idling speed of the old gl8)

Generally, the Buick gl8 four-cylinder engine model has a normal idle speed of 800 rpm, and the six-cylinder and above models have a normal idle speed of 600 rpm, which is lower than the cold start 1000 rpm. In addition, when idling, it is normal for high-power vehicles such as air conditioners, steering, headlights, etc. to turn on power consumption, and the idling speed will increase.

The idle speed of most models on the market is different, even when a car is cold or hot, the idle speed is very different. The special feature is that the idle speed is very high in cold state, about 1300- 1500 rpm. The main reason is that the idle speed of the cold car controlled by the engine computer is too high. The purpose is to make the water temperature reach a relatively high state in a short time, and then reach the normal working temperature of the engine, thus greatly reducing wear and reducing the emission of polluted tail gas. The lower the idle speed, the better. Generally speaking, with the increase of the water temperature of the automobile engine, the idle speed will tend to be flat, and finally it will return to normal speed when the automobile is hot. So how many revolutions is the best idle speed, and the lower the better? First of all, we should know that the idle speed of a car is the lowest speed set to ensure that the car can run smoothly without stalling. As long as these two conditions can be met, the lower the idle speed, the better. Some people say that their cars are idling at 500 rpm. Is there a problem? In fact, there is absolutely no need to think so. As long as the car engine can run smoothly, there is no flameout problem and no jitter, this is a good state.
