1 1 Why is the throttle of the Accord broken?

1 1 accord The reason for the broken throttle body may be mechanical failure, dirt or improper adjustment. The damaged throttle will cause the vehicle to fail to start, the exhaust pipe emits black smoke, the idle speed is high, and the acceleration is not smooth, so it needs to be replaced in time. The performance of throttle failure includes: the engine idle speed is unstable, the idle speed continues to drop, and the engine is difficult to start, which is the cold start difficulty.

Throttle maintenance

Observe the tachometer pointer. When the pointer quickly drops to 1000 to 1200 rpm, the pointer will pause a little, and then drop to about 800 rpm, and the idle speed will be stable. At this point, the throttle is completely normal. When the pointer quickly drops below 800 rpm or even 700 rpm, and then slowly rises to about 800 rpm, the idle speed will follow from small to large, so congratulations, the throttle has been seriously fouled and needs to be cleaned immediately.
