Tengfei 4G94 throttle cold car idle speed

When the vehicle is cold, the idle speed is generally below 1000 rpm, and most of them can meet the demand by maintaining 600-900 rpm.

The idle speed of each car is different, and the idle speed of the same car is different under different conditions. In the north, especially in winter, it is easy to soar to 1000 rpm at first.

The so-called "idle speed" refers to a working state of the engine, which generally refers to the state that the engine works at the lowest speed that can run normally when the throttle is completely released and the vehicle speed is zero. The manifestations of abnormal idle speed are: dipstick jitter, expected idle speed jitter, and abnormal body jitter. Whether it is a cold car or a hot car, once the body jitter is different from usual, it is likely that there is something wrong with the idle speed.
