what do u think it is?
i have a 2004 f-550 service truck. it has 192,xxx miles on it. it just had the egr valve, egr cooler, oil cooler, and #8 injector replaced about a 1,000 miles ago,was driving home from work doing about 75 mph then slowed down to about 20 to make a turn. it started running rough like it was running out of fuel and wouldnt take any throttle and died. i clicked it in neutral while coasting and tried to restart. it let out A LOT of white smoke or steem couldnt tell. then tryed againg and it hyd locked. let sit an cool still locked. the water level didint apper to be low. took the tank cap off and still had a lot of pressure on the cooling system. any guesses to what it might be. they should be taking it to the shop today. will let yall know what they say. no im driving the old trusty 97 7.3 service truck.
