2002 ford f250 diesel powerstroke truck cranks idles rough when cold but when you take off when cold it will die but when warm it will runs ok sometimes it will loose power and puff white smoke out and die out
If it's a 6.0 Litre diesel, either get rid of it as soon as you can, or pull engine out and install new head gaskets, with $500 worth of head gasket studs. Also install a EGR elimination kit. These two things claim to make it a "bullet proof" 6.0L diesel. Ford quit using this engine. It's only used from 2002-2007. The EGR could be sticking causing all these problems.
Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day
