The Firing Order on most 4 cylinder engine is 1,3,4,2. The Firing order is most often in a clockwise direction on the distributor. It can be helpful to mark each spark plug wire before replacement. You can use masking take or my personal favorite, the paint marker. I most cases it is best to replace one wire at a time. This can help prevent placing the wires in the wrong spot.
