was out with a few a friends tonight, got in the car to come home and the chek engine light was on. only 'bout a 5 minute drive home, but by the time i got home there was a pretty strong smell of sulfer in the car. the idle is a bit chuggy when you first put it in gear. this just started tonight... any ideas what it could be? I know the obvious answer is to take it to the dealer to get the code, which i will do, but i cant do that till tomorow, and i'm a tad worried.... it is about -20 here tonight, but i dont think thats got anything to do with it since its warmed up from about -30 the past couple of weeks..
