If after replacing these parts it runs worse, then you may have introduced a new problem into the car. Diagnosing this type of issue would require performing several tests and inspections to determine what is wrong. Check for vacuum leaks, make sure the plugs are installed correctly, and you still need to verify that the new injector is operating properly.
