all emissions testing is done through a computer so its kind of hard to get around it.
So if there's no sniffer test, technically you pass if there's no CEL?
If you run catless but with the non-fouler and you don't run any CEL, you should pass, right?
Visual and OBD-II only here, at least in Alexandria.Going off of memory here...
In VA there is supposed to be a visual inspection of the catalytic converter system. So, even if you pass the OBDII readiness test, you can still fail the visual inspection portion of the test. Also, don't certain regions in NoVA require sniffer tests? I know in Hampton Roads there was no sniffer test, but they were supposed to do visuals (passed my old P5 with full CS exhaust).
