06 duramax diesel running terrible....
my dads got an 06 duramax 6.6l things running terrible.... he siphoned some fuel into it and turns out it had water in it. water in fuel light came on, we shut it down pulled fuel filter turns out their was almost as much water as diesel. we ended up actually taking the fuel tank off the truck and emptying it out wiped the inside out with a rag, and blew air threw the fuel line to clear the line up to the filter.all back together things skipping....has like no power barely shifts gears it is absolutely struggling. check engine light is on (water in fuel light never came back) we havent got the code read yet but any ideas wtf happened? injectors? the transmission only shifts if u let off the gas and then get back on it at high rpms...trucks got 75k on it still under warranty so will prlli end up goin to the dealer but still any ideas....thanks
