Hello everyone, I just came back from a 3 hours trip I have a 2001 cavalier, everything was ok during the whole adventure, except off course, for the 8 inches of snow, going and coming back, just before a got home, we hit heavy traffic, that backed me a good 2 hours, suddenly the tc light comes on, so a turn off the car for 30 seconds then turned back on, only this time the engine light was also on, do guys think maybe some wheel sensor is cover by ice or something like that? I have never used trac control as much as today it was very slippery, thank for your comments...[&o]
