Reving the engine in neutral or in gear will not simulate the conditions of a car accelerating, cruising and coasting accurately. The most accurate way to perform an Etest is by using a Threadmill.
I know, in my area anyways, I have not seen an Etest facility equipped with a threadmill. Is a threadmill a common sight in Southern Ontario? I have 2 vehicles so, every year or so, I witness the Etest technician reving and idling and taking samples that he thinks look good. Some places are only concerned with pumping cars thru to collect their fee and there's no faster way to do this then with a "Pass", right?
One thing is sure, if the Etests were done using the required tools and techniques, a lot more cars and trucks would fail, requiring emisions repairs.
