Does it literally sound like half the engine is running? A common problem is the UVC (under valve cover) Wiring harness gets burns up. The easy way to test this to unplug the wires that while it is running to see if it gets worse or stays the same. That will tell you what side is burned. There are four plugs, two on each valve cover. If it gets worse when you unplug you know that was working before......if it stays the same you found your problem. Let me know if you have more ??.

I had this wiring problem with my 96, but it would run real rough as it was only running on 6 cylinders.

Does it run real rough (as if the motor is missing), or does it just run sluggish? I'm guessing if just runs sluggish then your wires may not be the problem.

And by the way, if it is the wiring harness, get ready to spend some money. The harness was only a dealership item when I had the problem and they wanted $550 for a new one.

Rack if you are handy with a wrench you can do the work yourself and save yourself some (alot) of money. I can help you out, I saw your message and will give you a call.

If you have a ICP code that is an injector control pressure sensor. The culprit is usually a broken o-ring on the sensor that is on the back of the high pressure pump. If injector harness is not problem pm me I have been working on these since they came out and have many hours fixing them. I have 17 years experiance as an auto tech.

International has a kit to repair the meltied plugs.

You might check powerstrokeshop.com for a price on the UVC harness if needed. They are a great source for Ford Dealer only parts.
