It did set a misfire check engine lamp once, the dealer explained "your spark plugs are broken" and they installed new ones. The car ran excellent when we picked it up, nice smooth idle, the car ran better than when we first picked it up. After a couple hundred miles the car soon began running like it had before but fails to turn on the check engine lamp.

Iffen you can take it to another dealership please do. If not check your plugs and make sure they are the right ones for the Sky you have. And there are numerous threads about the plugs. Search sparkplugs and you will see the current number....Skip...
