In VA the inspector must look for visible smoke. If yer smokin', you
don't pass. I've heard of some pretty expensive vehicles failing
because of a little puff after idle. I think it's funny how diesels
don't require emissions inspection. My kid's got an old Mercedes that
really stinks when you step on it. Is this because the exhaust is not
as toxic as gasoline or is it because there aren't any effective pollution
controls for diesels?
