MY 1998 3.3 Caravan runs like a top with only 88,000 miles on it. The only issue is that if I warm it up on these really cold mornings, the check engine light comes on. Diagnostics show no code. If I reset it, the light will not come one if I just start it and go. Any suggestions? Thanks and Merry Christmas!!

 

Could be a non-generic code your particular scanner cannot handle. I'd have someone with a dealer level scan tool take a crack at it.
