Need help with a car purchase that was already made

I purchased a 2010 used Chevy Equinox with 49,000 miles on it. As soon as I drove it off the lot and stopped, it started to idle funny. The car started shaking uncontrollably and the lights started to dim in time with the shaking. It felt like it was going to stall, so we gave it gas. It happened again that night, so we took it back in. They still can't find a problem with it. Our salesmen said"it has an eco button on it, and that makes it do that" ???? Anyway, they will call me today later, and I'm not sure if this is something that I should take and hope it is OK. Or if I should give it back? Any idea what this might be, and why they can't find the problem? We have a powertrain warranty, but I hear it doesn't cover much if something should happen.
