Question Injector stickage?

So, I have my 2004 Excursion with 207M miles on it. I was noticing just today and thinking "Wow! This thing is running great!" Smooth as can be, engine just sounds happy. Not 10 minutes after that, it starts missing. Runs like one cylinder is out. No noise, no smoke, just acting like an injector is sticking. I changed the oil about 2 weeks ago, so the oil is nice and clean. Rotella T6 Synthetic with 2 bottles of RevX. I'm assuming it's one injector. That's how it's acting.

Here's my question. I don't want to just throw $1600 in rebuilt injectors in it. They supposedly were replaced about a year ago just before I bought the truck, but of course, I have no proof of that. How can I find out which injector is bad? As you all know, it's not as easy as the old GM diesels where the injectors were on the outside of the engine and you could just cap off one at a time until you found the bad one.

Any help would be appreciated.

Took it in the Ford Dealer. #8 injector gone. $568 total. Not worth my screwing around with it, so I'm having them do it.

I think I'll change the name on this thing to Maseratti.
Runs great as long as you open the hood and throw wads of cash in there...

Well, here we go again... Ran great when I got it back from the Ford dealer. That is, for less than one day. Missing again. Going back to the dealer on Monday. Look for this truck on a Craiglist listing near you soon...
