You may need to pressure test your hpop system. An oil leak anywhere in the system can cause injector codes to pop up. Before you go to that trouble though unplug the injector and make sure the pond in the four wire harness for the injector didn't push in and the wires in the main harness aren't chafed or damaged in any way.
