Has anyone had any experience with the new emission testing while they had MIL's installed on their car? For those who don't know what I am talking about...all cars 96-up no longer require to be run on the rollers (kind of like a dyno). The emission testers will simply plug into the OBD II port and be able to read your emissions. However, I have heard that they can tell if the computer is being tricked by the rear MIL's or if you have a chip installed to delete the check engine light. Can anyone shed some light on this situation? Thanks.
