Shaking Truck Upon StartUp: 1997, F-250 Heavy Duty Turbo PowerStroke Diesel. I am having problems with my otherwise extremely dependable F-250. About a week ago, I started the truck, it started, but started to shake while it was idling (similiar to when it seems to not be getting enough fuel). This happens every time - whether the truck is cold in the morning or even if its warmed up (like running for 25 minutes on the road). When starting the truck and I step on the accelerator, the truck seems to settle out (does not shake), but when I ease up on the accelerator it starts to shake again. Also, this shaking will evenutally go away if I let the truck idle long enough without any intervention (i.e., step on the accelerator). I have timed it; I've started the truck and just let it shake, it will shake anywhere from 10 seconds to just over a minute, typically it is about 20- 30 seconds. I have changed the fuel filter, but no go. Help??

Did you try turning the idle up??? I'm not familiar with the diesel version of this truck but it sounds like at idle the engine is not being supplied with sufficient fuel. Let me know what you figure out.

Sound live you have some bad injectors, you can plug to a code reader and see which are not firing.
