Ok so we have a 2005 chevy silverado dually 3500 duramax diesel...the engine is making an awful puttputt noise and when you hit the gas the truck will not move, it won't even rev up when you hit the gas. this is a serious problem because we need it for work purposes and all the mechanics say it's gonna be about a week before they can even look at it. so id anyone has any ideas feel free to let me know. thanks.
hope
