'04 Lumpy idle and white smoke

[Michael29]

Hi, I have a 2004 F-250 super duty king ranch.

The truck has began Idleing very lumpy and spits out a lot of white smoke from the exhaust. Once you get driving, the truck is perfectly fine. I have been told that its possibly the IPR (Injector pressure regulator). But since its just a funny idle, I think its maybe not that serious.

Any help?

Only do it when it's cold and clear up as truck gets warmer?

Its pretty much all the time when its just idleing, ive seen no change with the climate

[dhanna6powerstroke]

Ever noticed any coolant loss or white residue around the degas bottle cap?

[Michael29]

not really, but then again ive never paid that close of attention. ill have to check, what would that mean?

You could have an EGR cooler issue. If you don't see any white residue you can check for a cooler issue another way. Get the nose of the truck facing down hill and pull your EGR valve out. Look down inside of intake manifold and see if there is any moisture. If there is, the you have an EGR cooler that has failed.

No problem. Update when you find out and I'll help you figure out your best fix. There are a few things you should do to that truck that will make it more reliable if you're gonna keep it.

Possibly bad injector overfueling, with rough idle. You need a monitor.

Sent from my phone that somebody didn't help me get.

Thats what I've been thinking, i figured it might just be dumping too much fuel into it, I appreciate all the help
