Hey guys

So I've been having issues with misfires in cyl. 4, and my next step is to see if the fuel injector for that cylinder is bad. Could I just take off say, injector #3, and swap it with 4, to see if it throws the misfire code on cyl. 3 instead of 4 after they've been swapped? This would diagnose if the #4 injector is bad or not right?
