thanks guys new to diesels the ebpv used to go only till temp gauge hit the first line then would work great now it takes it till half way between the c and h before it will quit closing and thats comming out of a heated garage where it has been all night.
Got a 1999 f250 7.3l first start it has lots of back pressure sound and is like that till temp gauge goes up to half if u step on gas pedal before it is warmed up has no power and blows black smoke once warmed up runs like a dream
