I too work with emissions, we have the latest & greatest IM 240, results are in mass, grams pollutant/miles driven. A passing standard for an 86 would be .8 grams per mile of HC. So do the math and see how much even clean cars emit in a 20K mile year, multiple that by 1.3 million cars that are OUR test area alone, one city in one state, then muliple that by a factor of 4-700 and one gets a general idea of why cars are targeted for reducing emissions.
its all in the numbers.

Do you know if the air pumps on later 103 engines inject air all the time or just during warmup? If the latter, how is it controlled? Is there an electromagnetic clutch on the pump pulley?
I don't work in automotive emissions now, but I did graduate research in the field at the University of Wisconsin Engine Research Center.
