I own a 1998 Chevy Express 3500. Recently it has been running very rough with a loss of power. The exhaust smells like gas and is sputtering a white "smoky" exhaust. We have lost a lot of power and our mpg's are way down. Today it stalled as we were driving down the highway.
We thought it was the spark plugs so we gave it a complete tune up and added a fuel filter. There are no codes coming up and everybody seems to give a different diagnosis. We're spending way to much money trying to fix the problem. Please help!
