My 03 HO Cummins with 28K miles had excessive engine knocking when the truck was put in to drive/reverse from neutral or park. The dealer has ordered a new fuel injector. Has anyone else had this problem? Thank goodness I'm still under warranty.
You are covered 4 100 k ... it's under Cumming warrantie . I heard of injector going bad , They get stock or clogged , I think is haze to do whit fuel ,you use any particular fuel station? Switch them ...That's my experience whit a 300 TD Merc. I use fill up at the same gas station and I end up changing the injectors in 6 months.
Better hope and pray that no one has to replace injectors in an 04 or 05. The injectors are in the thousands. I got my 04 used with 7000 miles on it. Had it for 2 weeks, someone put about a gallon of water in the tank one night. Between the tow, the cleaning of the tank and the injectors, it was about $5200.00. Thank god for comprehensive coverage.
They replaced one of the injectors (for free as its still under 3/36) and that fixed the noise. They claimed it had a carbon buildup due to excessive idiling. They said the engine had idled for 300 of its 900 hours. I do a lot of city, stop n go driving, but 1/3 is not from idle. They also reccomended I use a fuel tank cleaner.
the idleing to much is their common response on the injectors.they have a problem and know it.the duramax guys have had this going on forever,and now that the cummins is common rail and uses the same cp-3 pump and injectors,its the same thing.imo,the fuel is just to dirty,causing these problems.the stock dura`s dont filter down to as few microns as the cummins system,and their problems seem to be a little worse on thier earlier models.as for the cummins warranty,there is none.dodge buys the motors without any warranty from cummins.the warranty is strictly dodge.and they do have a clause about not covering damage due to contaminated fuel or water in fuel.................bama
