[AT] Tractor hauler question.

Tue Aug 26 05:00:54 PDT 2008

Well, I figure my chainsaw and lawnmower and the gas cans that feed
them are putting more evaporative emissions into the air than several
hundred automobiles, so, yeah, I tend to agree with you about the lack
of PRACTICAL ramifications.  If however your state has an emissions
inspection program, typically you cannot pass if your Check Engine
light is on for ANY reason.  (You already know this, just stating it
for the record))
