Hi, I recently bought a used saturn. I've taken it to get smogged and the emissions passed with flying colors. But there is a second test on the monitor system to ensure it is functioning properly. Mine appears to be disabled in some way. A few "non-continuous" monitors are in the "ready" status, but four others are not. The tech recommended to me that I drive 25 miles and come back. I've done that twice and the same tests are "not ready" both times. The tests: Catalyst, Oxygen Sensor, EGR System and the Evaporative System. I doubt it is the electrical system due to a lack of any other symptoms. Any clue? Is it that the comp. chip is acting up? P.S. The continuous monitors are all in "ready" status.
