you don't have to spin the tires to make emissions, i thought everyone knew that, i did the emission on my mom's jeep with four wheel drive.

Your state may not perform loaded tests such as an IM240 test.
revving the car engine in nuetral is not even a 5 percent engine load situation.

well in mass with my AWD thats what they had to do to, just reving it. Then when it failed the guy then did it without doing anything, just the sensor in the pipe, and i still failed by double the state standard . I got rid of the car before i had it fixed but im pretty sure it was a bad cat.

of course the car expells gases when its not moving; its just not anywhere near the amount that it is under load. you cant have a real test without load conditions.

what does your state have then? here in washington we don't need that, and when spinning the wheels it's the same load they keep it at the same rpm's wouldn't it bee the same load when the engine is working the same. once the wheels start going the load goes down from force of gravity.

higher revs are not what creates high levels of NoX; thats caused by high combustion temps, only reached at high load situations.
An IM240 test is the nation standard in polluted areas. If you dont live in one, you probably will someday. check out a couple links for more information.
