check the coil. i had the same problem on my 93. my coil was loose around the iron core and it missed once in a while. eventually the coil died and i could barely start it. i thoguht it was my MSD ignition acting up but i took it out of the loop and the stock ignition wouldn't even start the engine. i replaced the coil and it was as good as new!

check the coil for mechanical damage/wear.
check the coil electrically too, the shop manual should have the specs on the resistances. measure it with a multimeter.

also check the plug wires, i like to put a bit of silicone semi-conductive grease on each plug connector.

i just noticed that you have a 98, so you have coil packs instead of a single one?
