Check engine light on only when cold
So another winter has set in on my 2003 v6 Accord, and this time around the check engine light now comes on when, and only when, the air temp is consistently below freezing. The car has 115k on it so it's no surprise that there are some gremlins now and then. What could be the cause of this one? It happens like clockwork, for the past 4 freeze/thaws we have had here in ohio any time it is in the 20s or below for more than a day the light comes on, then stays on until its in the 30s or 40s and the light promptly goes away. It runs fine the whole time, although it has started giving me trouble with warm starts where it doesn't want to start if the engine is in the middle of cooling down (turned off for about 10-30 mins, not more not less).
The weird thing is that I have a Davis CarChip that reads ODBII codes, and for some reason it doesn't see any code when the light comes on. So, without taking it to a dealer or getting some keen insight from some of you guys, I am not sure how to get this resolved.
