Vehicle runs great; after starting newly each day, and under load there is an acrid metallic smell that permeates the vehicle. It lessens with driving, and after running for awhile, it only occurs under heavy load, like going up a steep hill. After sitting overnight, the problem reoccurs. The exhaust system is fine and the local Chev dealer drew a total blank on what it could be.
