[DML] Re: Does Lack Of Smog Pump/ EGR Cause Long Term Damage To DeLo Converter?

["Dave Swingle" <swingle@xxxxxxxxxxx>]

Based on the fact that many properly operating and tuned DeLoreans 
are wearing their original Cats well over the 100K mile design 
target, I'd say the design was sound. That's probably longer than 
most of those smog pumps last, at least on the cars I've seen and 
owned.

Don't mistake lack of maintenance and age-related deterioration for a 
design flaw. We're driving these cars 12+ years after they were 
supposed to be dead. Sometimes we forget about that.
