PROBLEM TO BE SOLVED: To provide a method and system of fuel injector operation. SOLUTION: A method and system of fuel injector operation is provided in which the electronic control module (ECM) reduces the number of injection signals sent to the fuel injectors. Specifically, the ECM selects certain injectors to perform a post injection during a specific engine cycle and increase the quantity of fuel injected by the selected injectors to compensate for the other injectors that are not performing post injections during that engine cycle.
