Here is a question for those that know how altitude affects a Vanagon, or
any other car for that matter.

We recently moved to Boulder, CO with our three cars.  Since the air is
thinner out here, do we need to have the air mixture adjusted (i.e., CO)?
Seems like our cars are running a bit funny since the move out here.  Seems
to me that we would need more air in the mixture than at lower elevations.

Anyone know for sure?
