I'd check #1 spark plug.
Usually a misfire code "fix" is a spark plug, spark plug wire, or a coil pack / distributor.
Keeping it simple...I'd go with the spark plug first and then look at the condition of the wires.
Hope this helps...
My Mazda MPV 2000, has misfire on #5, changed plugs, wires, coil but still runs rough and lots of gas smell
