Neil,
I don't think this is the problem with my truck as the surging with
cruise only happens after it's been set a while and then happens continually
and sporadically. However, I'd love to know the unlearn, if you'd be so kind
as to send it.
And Andy,
Do you have a pointer to the Durango issues/resolutions you are
referring to?
thanks,
Rick
