well the beast quit on me this morning early going down the interstate... had it towed to the dealer but sure do not trust them. . running about 65 it sputtered a few times and smoked big time and just quit... tried to crank several times and nothing... it tries to start but runs like on one cylinder and smokes really big time... . checked all the intercooler connections and they are ok... no water in fuel filter and no fuel leakage that can be seen... does it sound like the lift pump... i changed the overflow valve about a month ago and it just did not seem to crank the same but its probably my imagination... and suggestions would be great... i am waiting for the dealer to call so i can go down there... not good.....
