GMC, flushing injector in Yoav

GMC, flushing injector in Yoav.
It may be time to flush the injector in the presence of the following signs: unusually long spinning of the starter, body vibrations, and reduced engine power. The injector flushing can be carried out using the fuel rail, when flushing fluid is supplied to the combustion chamber through the rail and the engine is running for a while. Ultrasound flushing is also possible. In the framework of the ultrasound flushing, the injectors are removed from the engine and placed in an ultrasonic bath.
