The spark plug wires run to the distributer , which on top of the distrib. lies the distrib cap and rotor.

Basically, number the wires with a marker and pull them off the cap... two screw hold the cap on, and the rotor sits inside of it.

As for gas treatment. Basic additive like Lucas or Gumout. Something you just add to your tank of gas

replace your fuel filter too if you've never changed it out. very neglected piece of equipment there.

Fuel filter is in the tank, non-serviceable.

Depends on the model year, I replaced my fuel filter on my 96, easy to do and really nothing blocking it so if you haven't done that not a bad thing to do.
