My SIverado which is under warranty starting losing 2 miles per gallon and it burning very rich. Tail Pipe black and leaving black on the bumper. Took it to Chevy dealer and the computer was not pulling any codes and they told me nothing was wrong. I know better and was wondering what the issue could be?

man, there are so many things that could cause your issue,just cause they can;t find a code doesn't mean there isn;t an issue,your right.the problem here is that you need to take it to a competent shop to get it diagnosed, but you should not have to pay because it's under warraunty.maybe try a nother chevrolet dealer and maybe you won't get such a lazy or untrained person this time.
