Hmmm...
What if you cancelled the insurance a month before it's up or before the emissions test, then reinsure it. They wouldn't test you since the due date isn't expired
I've only heard this idea, not done it. (We have emissons testing) I "broke down" and humbly took it to a shop to get it aircared. They have so many tricks up their sleeve, I'd do that. One shop got my boss' 77 mifiring van to pass...
