emissions oh no fincal notice and three days left

[PKRWUD]

Illinois is in the process of becoming the most difficult state in the nation in which to pass smog. They already have a program underway in which they "talk to your ECM" to get a history on your vehicle, and find out if you've made any mods in the past, but that only applies to about half of the newer vehicles. I don't know the specifics for your year, or your area, but I would go in expecting the worst. Either way, set your timing at 10 degrees, reduce your fuel pressure, change your oil, and get the whole driveline as hot as you can just prior to the test.

Take care,
