For a 1997 Cavalier 2.2, the firing order is indeed 1-3-4-2, but the spark plug wires should be connected in the same sequence as the firing order. This means you should hook up wire number 1 to the corresponding cylinder, followed by 3, 4, and then 2, in that order. Make sure to connect them according to the cylinder layout, with cylinder 1 typically at the front of the engine. Always refer to a repair manual for specific wiring diagrams if needed.
