It is going to affect no one. That thing was posted even before Crist became governor, even before last election. As I mentioned, anything like this would have to go through the legislature first (not via executive order) as such program would have to have a source of funding. Moreover, no state official would go around passing these things from shop to shop...that also requires funding.
From what I have seen, most issues have been gutted precats and one main cat...in that case problem would be HCs (hydrocarbons, a.k.a. unburned gas).
HCs are problemo numero uno when it comes to not passing.
That garbage about how Florida never tested NOX and that was where the problem was is also BS. Most of that was coming from buses and diesel rigs, not cars.
