Back when I worked for the school district, they had throw-away carbon monoxide indicators that they placed in buses when drivers complained of headaches etc. A couple years back I hunted everywhere locally for one of those, but couldn't find them. I was shopping in my Aircraft Spruce catalog for a new throttle cable for Bussy when I stumbled accross them. The 18 month rated one is priced at only $5.99. Anyone who suspects they're getting exposed to carbon monoxide especially while driving what we drive ought to get one.
