Twenty years ago I lived in Maryland for a few years. They have stringent safety inspections and required emissions tests. When I moved there from Texas I had a 1987 Honda Accord that had passed both tests in TX. During the first safety inspection in MD they dinged me for having a spot in the rocker panel that had rusted through. Apparently that's a violation because the exhaust fumes could enter the car's interior. I patched it with body puddy, took it back and it passed. But a few years later I couldn't get it to pass emissions. It failed because of high hydrocarbon output when decelerating. I had a newer car by then so I donated the Honda to our local NPR station.
Interestingly, at the testing station they provided the printout from the tailpipe sniffer. It showed graphs for carbon monoxide, hydrocarbons and something else, maybe NOx (can't remember). I compared the output from the 87 Honda with my newer 96 Camry. Looking at the graphs it was clear that the four cylinder Honda was dumping over 20 times more hydrocarbons than the six cylinder Camry. I tinkerer with the carbureted Honda but after a couple of failed tests, I gave up and donated the car. In 2008 I moved back to Kansas and I enjoy not having to comply with any inspections!
