as "special" as the Z32 was/is - I'd guess that other vehicles are affected too. IMO the reason it applies more to the Z32 is that after 10 - 15 years most stock vehicles are in the junkyard. Eventually the injector problem will be solved by vehicle attrition as only new-style injectors will be on the road - unless you are talking about a particular car that enthusiasts have kept alive - and I suppose even then the old style injectors will be out of production and even the purists will have to convert... As far as the petro/auto companies are concerned this is a problem they can solve by "extinction", ie if they ignore the problem long enough it will just fade away.
