You need to check everything from the fuel cap to the carbon cannister to a failed purge valve. See diagram of EECS.

On a car your age if the plugs are good the likely cause of a misfire is plug leads. Replace them. After that could be a coil pack. Mark & swap coil packs around & see if misfire changes cylinder.

Good luck!
