2000 Daewoo Leganza

1-4-2-3 is the firing order as I have shown in the pic. The cylinder numbers are just like any other four cylinder - Standing in front of the vehicle looking at the engine left to right 1-2-3-4. I assume you are wanting to replace the wires and plugs on your car? If so, just match the wires cylinder 1 to coil 1 cylinder 2 to coil 2 and so on. Any questions let me know.
