rough idle and check engine light

Hi guys,
Last weekend my truck started to idle a little rough. It was most noticeable a red lights (in drive). The plugs and wires have about 8K miles on them. On Tuesday the check engine light came on and then went out on Wednesday. Took the truck to autozone and the code reads PO302 (#2 cyclinder misfire I think?). Any thoughts on what the root cause is? The truck is a '97 F150 4X4 with 4.6L engine. Approximatly 100K miles on it.
Thanks

If the plugs and wires were good and done correctly, the next thought would be the coil, but injectors and other things can also cause this.
