I would wonder the same as above? You would think water would smell like gas coming out of the exhaust. Or maybe you have a cylinder not firing.

well you can remove your both valve covers and start up your truck and let it idle then go see if all your valves are moving if it is then i really dont know what it can be. if you still having gas come out then just google your problem....
