What should I do if the fuel consumption is high after cleaning the throttle and nozzle?

There is no sludge blockage after cleaning. If the throttle valve still maintains its previous opening, the intake air volume will be too large. As a result, the engine will shake when starting, the acceleration will be weak, the fuel consumption will increase, and the engine fault light may light up.

When there is a problem, you need to go to a 4s shop or a professional repair shop to reinitialize the throttle and computer. After the initialization is completed, the normal operation of the engine can be guaranteed, and the phenomenon that the fuel consumption increases and the speed increases after the automobile throttle is cleaned will disappear.

Initialization can be performed according to the following steps.

1. Insert the key, turn the ignition switch to the M position, and wait for about 20 seconds.

2. Press the accelerator to the end, hold it for about 10 second, release the accelerator, turn off the ignition switch, pull out the key, and the initialization is complete.

Extended data:

If the throttle valve is not cleaned for a long time, the opening error of the throttle valve will occur, and the sludge formed by dust will reduce the sensitivity of the throttle valve. At the same time, sludge will block the idle passage, pollute the idle valve, and affect the power, acceleration performance and fuel consumption of the engine.

It will also cause air with impurities to enter the combustion chamber of the engine. These two results will lead to abnormal engine operation, mainly manifested in unstable idle speed, sudden flameout, reduced power, even difficult starting and increased fuel consumption.
