Have them clean the throttle body. Run some Techtron through it with a full tank of fuel.

So they should put gas that costs 30 cents more per gallon in, just to make it run better? I surely hope that isn't the fix. The car is rated for 87 octane, and should run perfectly on it. They need to try a different dealer and get it fixed properly. No new car should run that rough, so something obviously is wrong with it, and the dealer doesn't want to help out with it. Those darn rip off GM dealers...
