With the Chevy Blazer, if the gas cap is loose, or a crack in the gasket, it trips that stupid light on. Then, your car won’t pass inspection, until they diagnose $79.95, the non-existent alleged problem.
Its just another tax to pay other people for something you don’t really need.
I’m so annoyed by this baloney that from now on when I park my car for the night, I’m going to take the gas cap off and let my gasoline fumes belch into the atmosphere, and destroy the planet. 🙂
P.S. After they turn the light off, you have to drive 200 miles to set all new codes before inspection the 2nd time.
