No that is not normal and is the sign of a dead hole. The fuel injection on that is referred to as Multi Port Injection. That means all of the injectors fire at the same time and at the same rate. What this means is that you can swap the harness connectors back and forth on the injectors and if they are all working as they should there should be no difference so long as they are all plugged in. All that being said, swap the connectors between two injectors and see if the miss follows the harness or stays in the same hole. If it stays in that hole then you have a spark or injector problem in that hole. With the car idling use a mechanics stethoscope or long screwdriver to listen to each injector individually, they should each have a nice distinctive "click, click, click" noise. Past all of that stuff you can do a compression test, both wet and dry, check your valve clearance, and check for a busted valve spring while you are in there. You could also go as far as swapping the injector from hole to hole itself to see if the miss follows that injector or not.
