Does anyone know the real skinny on the new emissions testing in Illinois? I'm sure some other states are doing the same. Basically up until Jan 04, if you had a 96 or newer vehicle, they would run an OBD test. They would hook up to your diagnostic port and then read out:</P>


1) The emissions MIL command - On or Off 2) Which, if any, fault codes are stored 3) Readiness monitor status.</P>


If you failed this OBD test, they would do a regular old fashioned emissions test.</P>


Now, if you fail the ODB test, you fail and have to fix the problem.</P>


What I'm looking for is if I'm running a non-cat exhaust and MIL eliminator setup, what you do think is best to do prior to emissions testing? (I currently don't have this setup, but I'm curious).</P>


I'm guessing that I should switch back to stock exhaust a few days before testing, clear the codes if any by disconnecting the battery, then drive around stock for a few days to reset the readiness monitor status(s). Or will the MIL eliminators take care of the OBD? I don't think Illinois does a visual, so I wouldn't be worried about that.</P>

I just had mine done in October. '96 and newer, all they do is check the Gas cap for leaks, and plug the OBDII scanner into the car. I checked mine before I went in, and didn't have any codes and passed. A friend of mine had his SES light on, borrowed my scanner, and cleared the codes while he was waiting in line. He shut the light off, and passed.</P>
