How to clean the fuel injector?

Before starting the engine, remove the fuel pump relay in the fuse box to stop the fuel pump. Because the fuel manifold is not connected with any equipment at this time, if the fuel pump continues to pump oil at this time, the fuel will flow directly from the fuel manifold. The way of "infusion" is to "drip" the car like a doctor in a hospital. The working principle is simply to replace the function of the fuel tank and the function of the fuel filter to replace the fuel. "Hanging bottle" refers to the use of fuel cleaning agent for engine operation. When working, the carbon deposit in the fuel injector is cleaned and discharged through the exhaust pipe to achieve the cleaning effect.

After the cleaning is completed, the next step is to step on the accelerator in neutral or drive at high speed on the open road for a few minutes, so that the cleaning agent can achieve sufficient cleaning effect and discharge the cleaning impurities through the exhaust pipe.
