How to judge whether the throttle should be washed?

Judge 8 conditions of the throttle valve to be cleaned:

1. Unstable idle speed: the idle speed of the vehicle is controlled by the throttle. If the throttle is too dirty, it will directly lead to unstable idle speed.

2. The fuel consumption of the vehicle increases: when refueling, the throttle position sensor will give a signal to the computer, and the signal received by the computer is the throttle opening. When the throttle opening becomes larger, more fuel will be injected. Once the throttle is dirty, there will be carbon deposits on the replica of the throttle, which will cause the computer signal to refuel slightly and lead to fuel consumption of the vehicle.

3. Turn off the throttle when driving normally, and the vehicle turns off: this is a serious performance of carbon deposition on the throttle. Turn off the throttle during normal driving, the vehicle suddenly turns off, or when shifting gears by manual gear.

4. No idling: The performance of no idling is that the vehicle at the refueling door is on fire, and the fire will go out if it is not refueled.

5. Slow acceleration response: I stepped on the accelerator and didn't accelerate immediately.

6. Power drop: Failure to clean the throttle for a long time will lead to an error in the throttle opening, which will cause air with impurities to enter the engine combustion chamber, thus affecting the vehicle power.

7. Affect the normal start of the vehicle: if it cannot be started or it is extremely difficult to start.

8. Observe the pointer of the tachometer: All EFI vehicles, as long as the engine is not loaded, slam on the accelerator for 3000 revolutions in neutral, and then suddenly collect oil. Observe that the pointer of the tachometer drops rapidly to about 800 revolutions, and the throttle valve is slightly dirty, so it is unnecessary to clean it. When the pointer quickly drops to 800 rpm or even lower, it slowly rises to about 800 rpm, and the idle speed changes from small to large, indicating the throttle. Million car purchase subsidy
