You have made this comment a number of times in the past and I am always curious. Why is mandating that something actually work for a reasonable amount of time a bad thing?[/quote]
People were simply too lazy, or cheap to get regular engine tuneups. The enviro-wackos jumped on that bandwagon to impose utterly ridiculous requirements on auto manufacturers, with no basis whatsoever in reality. The manufacturing costs for "emissions" parts such as electronic controlled carburetors, for instance, went up exponentially. An "electronic" Quadrajet cost around $600.00 to replace in the mid-1980s.
