I have a 2001 7.3 the outside airtemp dosent seem to make a differance. When i start the engine for the first time of the day and try to drive it it will work ok for 1 to 2 minutes then it just shuts down like there is no fuel getting to it. The motor dose'nt die but i need to keep the throttle open all the way to keep it at about 800 rpm then slowley it will recover sometimes emmitting the blue white smoke. This will happen anywhere from one to three times. Once the engine is up to operating temp or it goes through its morning regiem it will be fine the rest of the day. No engine codes to referance and the batteries are new and so is the fuel filter. I need some ones thoughts as there is very little money to start just swapping stuff out. also the cam position sensor was changed out last year.
