Sorry to hear that...

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!

 

is this an 05 only problem? I'm curious if i need to do this on my 04. I'd rather not replace then engine!

 

Could this probelm apply to an early 06 model?

 

I hear yes, but the 06 isn't covered by the extended warrenty.

 

Stupid question but is there a way to tell if you have the later 05 injectors in an early 06?

 

You MIGHT be able to compare part #'s because the suppliers changed, but I am not positive

 

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.

 

Where is a good place to get replacement injectors? And what is the best brand to get oem or aftermarket?

 

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.

 

x2 anyone??? i have some extra cash right now and would love to change these out?

 

x's 3....where is the best place to order a set from?..and does any know specific build dates that effect these injectors?...my truck has a 04 build date but was sold as a 05...

 

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.

 

The stock replacements you will find anywhere will be the improved parts. Try rockauto.com.

As I said in the other thread - Motorcraft. You only need to ask the question once.
