It is the 5.3L engine’s firing pattern can be described as: 1 piston is turned off at TDC even though the following the first is triggered. This occurs following the stress from the absorption manifold rises. Since this occurs the fuel injector will not be active until the tube has achieved TDC. The gasoline in the tube that may be not activated is dragged in the tube and after that ignited after which burnt for repairing normal engine functioning.
It will be the 5.3L engine’s firing style is among the most elaborate facets of the LS-group of engines. The fuel injectors are changed in a way that the PCM has to be familiar with which injectors are performing and which aren’t.
