The new Regal consumes a lot of fuel after washing the throttle. Why?

Initialization is needed after cleaning, because the computer has a memory function when adjusting the throttle opening. There is no sludge blockage after cleaning. If the throttle valve still maintains its previous opening, it will cause excessive intake air. As a result, the engine will shake when starting, and the acceleration will be weak, and the engine fault light may light up. Initialization method: Turn on the second gear of the key, that is, the gear indicated by the instrument is fully lit, then wait for 20 seconds, press the accelerator to the bottom for about 10 second, release the accelerator, turn off the ignition switch, and pull out the key to complete initialization. After initialization, you have to wait a while before you try to ignite. Generally, you can wait 15-20 seconds, and then ignite to see if refueling is normal. If you have any other questions, you'd better go to the 4S shop to ask.
