They all have optisparks.  The 95+ have a vacuum host added to evacuate
the optispark and hopefully keep it dry.  I have just installed a fully
electronic ignition system that tricks the computer into thinking it works
like the optispark.  I am still uncertain how well it is working.  It
siginficantly changed how the car was running, in terms of how much fuel
the car was used at idle.    The web page for it is:
www.electromotive-inc.com.   The price for it is $799 (with the hardware
to fool the optispark computer).  Without the optispark fooler is is
somewhat cheaper.  I will update everyone on how well my work with this
thing goes.
