What happens when the throttle is dirty?

Unable to start, high idle speed, poor acceleration, etc.

If the throttle valve is cleaned frequently or regularly, the coating on the throttle valve will be cleaned quickly, gum and carbon deposits will be more easily attached to the throttle valve, the throttle valve will be dirtier, and the cleaning cycle of the throttle valve will be shorter and shorter.

If the lubricating oil at the throttle shaft is not cleaned, the throttle will not run smoothly and often get stuck, and then there will be failures such as failure to start, high idle speed and poor acceleration. This situation can't be repaired, only the throttle valve can be replaced.

Mild carbon deposition can be ignored, and the engine control unit will automatically adjust the throttle opening to keep the idle speed stable; If the carbon deposition is too serious, which is beyond the adjustment range of the throttle, the engine will have some faults such as idling jitter and weak acceleration, so it is really necessary to wash the throttle.

Extended data

The importance of the throttle valve to the engine, although the air first passes through the air filter element and then enters the throttle valve, due to many factors such as air velocity and baffle angle, some dust in the air will slowly attach to the throttle baffle and the surrounding space. Over time, more and more impurities are attached to the throttle, which will affect the intake of the engine and cause the acceleration to be weak.

Vehicle idling jitter is because the throttle is too dirty, resulting in a particularly small gap in the baffle, so that air can not flow into the intake pipe of the engine in sufficient quantity. The ECU of the engine injects fuel according to the air quantity. When air enters, less oil is sprayed naturally, and the engine will be unstable, as if it were going to stall. So it is very necessary to clean the throttle.
