    I have a 1997 F250 powerstroke with the same problem. Idles ok when cold, drives beatifully but when it warms up, the idle is so rought my hand and legs can be seen shaking. We've replaced the lift pump, filters, even a fuel injector that came up as a code. We haven't tried the intake hose and throttle body but will do that next. Any other suggestions?

Engine running rough


Need more information.
6 or 8 cyl engine?
Do you notice the rough running only at idle? Only when accelerating? Is it worse when the engine is cold or warm? Is there a check engine light? (if not, there likely will be one soon).
Did it start doing it after a service or after filling with fuel?

Could be one of many things:

-Clogged fuel filter
-Leaking fuel line
-Bad fuel pump
-High or low oil level
-Overdue oil change (Will explain both these possible causes later)
-Bad high pressure oil pump, ICP sensor (injection control pressure sensor), ICR (injection control pressure regulator), or bad HEUI injectors, or oil lines
-Leak in the high pressure oil system (unlikely because you would have noticed this... This does not go undetected as the underside of your vehicle would be literally covered in oil and dripping in a very short period of time after the leak develops)
(Powerstroke engines use a HEUI fuel injection system, "Hydraulically actuated/electronically controlled unit injection", which relies on a high pressure hydraulic pump that uses engine crankcase oil and pumps it at high pressure (500 psi or so). This oil is sent to your fuel injectors to provide means for actuating them and pressurizing the fuel into the cylinders. High or low engine oil level, or old, diluted, additive depleted oil will cause this system to aerate the oil and result in poor fuel injection capabilities)

There might be other causes but this is the Powerstroke`s weak point... The HEUI system was first designed by Caterpillar, which makes a lot of excellent/bulletproof HEUI based engines, both in passenger vehicle and heavy trucks and equipment. The Powerstroke is an engine designed and made by International Truck and Engine, which cannot seem to make a HEUI engine, in any market, whether passenger, heavy truck, or equipment that does not suffer from fuel injection issues.
