: I had never heard of putting the car on rollers, here in Mass they have some grease monkey throw a collection pipe over the tailpipe and let the car idle for a minute or two while they check.

Basically take two large rolling pins (like the was you use to roll dough with) place a tire on top of them. Wheeels spin----> move roolers. Another way of think about it, picture a giant Treadmill for a car, except that a rear wheel drive car has its front wheels on the groundand rear on the treadmill.
