I had prior problems similar to what you are having with engine code 45 (leaky injector). Injector #3 was shorting out for me, I had to replace the clip and injector to fix it. If your car feels weaker its possible you are running on 3 cylinders. Best way to test it is let your car run on idle and unplug each injector then plug back in one by one. If the engine responds to the unplug then the injector is working, if you unplug one and there is no change in the way the motor reacts then its possible you have a bad injector. Hope this helps.
