my car wouldn't start the other day because of the cold (-30) so i boosted it and it started fine. when i went to start my car today, the check engine light is on but it drives fine. does anyone know what could be wrong? thanks

 

You need to get the code checked..what year is the car?

 

its a 99

 

No guesses as to what it may be, but I know that autozone and advance will generally check your car for free to let you know what the cel is for. Good luck!
