why does my check engine light come on in my 2005 Chevrolet 2500HD PU after driving long distances

Asked by Jan 21, 2013 at 05:23 PM about the 2005 Chevrolet Silverado 2500HD 4 Dr LS 4WD Crew Cab SB HD

Question type: Maintenance & Repair

it seems as though after driving long distances that the check engine light comes on.  however, not
when i'm doing short trips just around town.  I would occasionally like to take the truck about a 4 hour,
round trip, but am not sure if it's safe or not.  No one can seem to figure this out.
