Injector Replacement Poll

[rbattelle]

Please answer "yes" if you've had at least 1 injector replaced, "no" if you have not had any injectors replaced.



I was just curious what sort of injector failure rate we're seeing.

NONE replaced for me yet

 

[DFrank]

still all good at 32K

I don't think there is an issue with the 305/555 engines. I have two of them with well over 150k miles combined. I think that when they went to the 325/600 power ratings the problem came up. In fact, so far I am inclined to think that maybe just the '04. 5 and early '05 trucks are suspect. I certainly could be wrong though.



I didn't vote yet as my '05 goes in for a bad injector diagnosis tomorrow.

I had one injector replaced at 12000 miles, it started showing signs at 7000 miles. It made things better, but still not quite right. I think I still have at least one more bad injector.

8700 miles of hard stop and go driving. Good so far (knock wood!)

What are the symptoms of a bad injector?

 

[RChamberlain]

I haven't yet but then I only got 1700 miles

I have had two replaced so far. Dodge called the other day and said number three has arrived so I will make a appointment for next week. The ones that have gone bad so far are: #1,#5 and now #6.

05 3200 miles so far so good

 

[RTillery]

41,000 and purring like a kitty. Consistently getting 20plus mpg.

 

[SRadke]

34k miles and I'm thinking I need a whole set. Something a little bigger and better ya know

PS, no failures with the stockers.

What are the symptoms of a bad injector?

I second that question.



Should the injector lines be smooth? I heard line 1 shakes a little bit but the rest should be smooth. Will you notice higher egt's with a bad injector? Lower fuel economy? What else should we look for? Is there anything that can be done to prevent an injector failure?



34k and no problems yet.

 

[DGFoster]

6000 miles so far,no problems. .

 

[nwjetboat]

I had #5 replaced at 18000 miles. .

 

[BHolm]

4800 miles on the '05, #3 was found bad. The tech claimed that most of the ones he had seen were #3 for some reason. He also mentioned that failures seemed sporatic and he had not had any "come backs" on replaced injectors.



No problems on my 2 '03s, 150k+ combined



My failed one was leaking fuel. This would cause it to start rough and smoke. It also had a noticably shaky idle like it was missing, and it was. I do not have gauges but I bet egt's were up, un-metered fuel will do that. The truck seemed to run normally off-idle but was really bad in gear at a stop light.

Number six replaced at 35000 mi. The noise was a knock ,cackle- clack, just off idle. Now its quiet just like new... ... ... ... . JIM

 

[nickleinonen]

none changed for me, but i suspect i have a weak one [i think #4] but i won't have a dealer look at it until summer and i will check the torque on them myself when the weather gets nicer [spring]

 

[RM]

none as of 44k couldnt be happier with it. Purrs like a kitten

 

[Mathew Clausen]

Swapped, not replaced

Mine had rod knocking type sound just off idle at ~25,000 miles. Found to be #6 cylinder by deactivating. SWAPPED #6 with #3 injectors and problem is gone. Can't figure out why it would have fixed anything - but it did.
