DTC P0201, P0202, P0203, P0204, P0205, or P0206
The engine control module (ECM) enables the appropriate fuel injector on the intake stroke for each cylinder. Ignition voltage is supplied directly to the fuel injectors. The ECM controls each fuel injector by grounding the control circuit via a solid state device called a driver. The ECM monitors the status of each driver. If the ECM detects an incorrect voltage for the commanded state of the driver, a fuel injector control DTC sets.
Test your fuel injector for cylinder #3 ! Do you know how to do that ?
You probably changed computers for nothing ! Check out this video on testing fuel injector circuits an checking computer driver that controls the injectors , Oh , by the way P0300 P0301 an P0302 are misfire codes , P0300 is a random misfire an the other two are for cylinders 1&2
