rough idle and intermittent white smoke

Finished my egr delete, new ipr, new icp, it was running pretty well for a bit then it started blowing white smoke when I get on the pedal from a stop. I drove it to the airport about an hour away and parked it. Drove it back to the house and halfway back I picked up a rough idle and it feels like it's missing. Now it's blowing light smoke at idle and then a big lingering cloud of white smoke as soon as I accelerate that stops blowing around 1600 rpm. My fuel mileage is starting to take a dump and it's an injector problem. How do I test it? This is my first diesel, hopefully I don't sound ridiculous

See if you can find somebody who can run a contribution test, that will pinpoint the offending injector.

Cool deal, if an injector is bad whats a good replacement? I've heard of sending them off to be rebuilt by warren diesel but I also heard it takes them almost a month at times to get them sent back to you. Trucks got 190K miles so I'm tempted to just do all 8...

If you want to stay stock then OEM from Ford is your best bet.

Sweet, I'll probably do that then. I just want to try and avoid having another one fail. Those suckers aren't cheap

I'm pretty sure Ford injectors get a 2 year warranty.

could it possibly be that my turbo needs to be cleaned?

Because you're going to have the turbo out anyway, I would spend the hr or two to clean it. Harbor freight has the best deal that I've found on those 1" arbor used in the cleaning process.

I just finished putting an injector in the 7 hole in my truck. Mine had 175k on the originals. After a EGR and oil cooler replacement, my truck developed a contribution/balance fault. I bought a reman from DCP and had a known, reputable shop put that one in. That shop didn't get it seated right and still had the balance fault. I figured if you're gonna do something, might as well do it yourself. Not knowing if the DCP reman was good or not, it was cooked black up to the first o-ring, I got a reman Motorcraft and put it in myself, and knock on wood, the truck is humming right along!

So I added rev X as a bandaid until I could afford all of the injectors. It idles better and runs better in general. So while I was under there in unplugged the VGT and drove it around the neighborhood. White smoke is gone, is my turbo shot? If the injectors were trash wouldn't they continue to smoke white after the vgt was unplugged?
