          Hi, Steve, Our Modis is at 10.2, I entered Your Cobalt into it and found "Evap Service Bay Test" in the Functional Test Menu. I'll see if I can find a GM product around here that is similiar to Your Cobalt. One of the guys here has a 2007 Impala. I'll take a look at that one first.

            Not sure but it may be your software, it's second quarter of 2008 for a 2007 car, it may not be in there.

              It's there in 10.2. It may not be in 8.2 because '07 coverage was brand new at the time. The test may have not been written yet.

                  love that new 10.2, and with the new smoke machine, having a blast.
