Emssions testing question

[AirWolf87]

correct me if i'm wrong but the southern NY counties (eg. Westchester and Putnam as well as NYC) and jersey do dyno sniffers in the tail pipe don't they? So even if you correct the computer code you'll still fail based on tail pipe emissions won't you? I've been gettin Inspections in Westchester county for many years and they've always given me my emmisions levels read out when gettin inspected, although I have never actually watched a vehicle go through an ispection.

for the old test yes. But as of this spring the test changed. I live in Suffolk, and the new obdII test you dont even put the car on a dyno. Its pointless, if the car already is equpt to throw a code if it doesnt meet emmissions, why test it twice? you just plug the test machine into the cars onbord diagnostics (which has its own emmissions) and thats it. So no, no they dont.
