I am the lucky one today. I was driving into work this morning and my truck started losing power and bucking and then the low oil light came on and also the check engine light. It sounds like the motor is in pieces inside. Time to breakout the injector leter and start the process with the dealer. I only have
63,000 miles on my truck and i am very disapointed.

I'm in the stuck open injector club too. Happened around 25k miles. They actually *did* replace all of mine at once (under warranty) and I've been trouble-free ever since (at 101k now)
Good luck!

Man, those are all good questions, and hopefully someone who knows will chime in. I have an '05 5.4, production date Feb. '05 so I knew I had one of the problem children. I'm probably repeating this story from earlier in this thread but, I went 190,000 on those injectors with no issues, and changed them at that point along with all 8 COPs, figuring with that many miles it was time plus 1 of the COPs was bad. $200 and 1 and 1/2 hour installation later for the upgraded injectors, and I am resting easy that I won't have any worries about a stuck open injector. Plus the truck literally runs like brand new with the new, clean injectors.
I guess what I am saying is, just because you might have the faulty injectors, doesn't necessarily mean you are going to have problems with them. And if you do have them or even if you don't know if you have them but yet can afford it, go ahead and change them just for peace of mind. You could even save some money on labor and do them yourself like I did (very simple to do, especially if you follow the Haynes manual), regardless of which, it sure beats spending thousands of $$$ on a new engine because it hydrolocked. My truck was way past the warranty range with that many miles on it so I couldn't take any chances.

Well add me to this list as well '05 FX4. At about 150,000km (94,000mi) started to get a misfire. Changed the plugs and checked the coil packs didn't fix a thing. Went to fire up the truck to take it to the dealership. The misfire turned into a banging. Thankfully this forum informed me of the extended warranty program. The dealership first told me the problem was a plugged cat and fuel control module. After I questioned that they told me it was top end valve train damage. After yanking the engine I found out the #4 cylinder bent the rod. Now I'm going through the diagnostics with the dealership to confirm an injector failure. It's been a fun ride thus far.

Just get the stock replacements, guys. With my experience after having my 05 hydrolock and snap a rod I had the 7 remaining replaced for peace of mind during the small block replacement, with zero problems since. Truck runs like a champ with 105,000+ miles on her.
