Check engine light when cold
 

My daughter has a 2001 SC1 with 75k on it now. Car runs fine, but check engine light comes on when started cold. Once it come up to temp. the light goes out on it's own. Started doing this about 2 weeks a go. Once at frist. For the past week every day when she starts it in the morning, and leaving work cold. I won't have a chance to look at it till next weekend. Thanks for any help

Need to take it down to AutoZone (or similar), and have the diagnostic codes read. Report them here, and we'll try to help.
