I agree with you as well but the car ran with this firing order when I first bought it. Thats odd at some point before my old ecm failed i switched it to the correct 4123 left to right of your looking at the car and it seemed to run just fine but then the ecu had issues I replaced it with a proper blackbox ecu i made sure. Perhaps the reason why the real 4123 firing order wont work as of now is because one of my coil packs is goin out? It sure does seem like itFiring order is incorrect. Looking at the coil pack, it goes 4-1-2-3. It is stamped on there as well. Cylinder number one is the one closest to timing belt.
