Removing a car's fuel injectors isn't very difficult.
First, loosen all the screws, the nozzle is very tight, use a little force, and the sealing ring must be replaced after disassembly and assembly. Then, remove the fuel rail, remove the fuel injector, clean the inlet and outlet of the fuel injector with carburetor cleaner, and then apply voltage to the fuel injector, the fuel injector inlet is connected to the carburetor cleaner of the thin tube, to ensure that the carburetor cleaning agent and the injector inlet do not leak oil until the fuel injector spray is small and uniform.
The oil injector is equipped with a rubber sealing ring, which cannot be aged and defective. The oil mist sprayed by the injector is like rain, and the oil mist sprayed by the injector after cleaning is in the form of mist. After observing the fuel injector up and down, check the sealing ring for oil leakage, and there must be no gasoline leakage.
