injector

  1. 07.5-09 3rd Gen 6.7L Performance Parts Discussion
    Will a S475 over a S366 be enough air to support 125hp injectors and dual cp3. Also will it tank gas mileage if so what injector can I keep economy but also make around 800-900 hp with.
  2. 98.5-02 Powertrain
    Replaced my injectors with stage 5 DDP's (that someone had sitting on there shelf never used is what they said) because i was having a misfire/surging going on since i changed them it'll fire up no problem but im having backfire/pop sound. So i cracked each injector line at the head 1-4 all...

    So I dont know too much about injectors and such but I have been on a few threads here. Truck has 184k with stock everything, the injectors used to idle roughly and shook the whole truck badly at idle and it almost shut the trucj off when it was fully warmed up last summer. Doesnt happen...

    Whats up yall, first time 12v owner. I recently bought a 94 with 150k miles bone stock. Ive been looking at an upgraded turbo, injectors, tuner, exhaust etc for towing about 3500 pounds every other week and driving it every few days to work in between towing. Ive heard all kinds of stuff about...
  5. 07.5 - 09 3rd Gen 6.7L Powertrain
    Getting a very loud rattle and loss of power if I accelerate hard, normally happens between 1500-2000 rpm, gets worse if I turn up the fuel or timing with my juice with attitude, I’ve replaced the fuel pump/ fuel filter/ fca/ and put in a rail plug, still no change. The truck will blow black...
  6. 3rd Gen. Performance Parts Discussion
    Hey all, new to the forum... I am beginning to build my 05 cr cummins, and as I order performance parts I could use some advice narrowing down exact parts. My goal is a reliable DD, used for occasional towing(3000-10000lbs), and obviously once its built some horseplay from time to time. HP...
  7. 3rd Gen. Powertrain
    Last week I was going up a hill and all of a sudden, I lost all power and the truck started smoking heavily (constantly). Checked my codes and it read a “P0304” code. Changed injector #4 the other day and nothing changed... still smoked and ran rough. I have absolutely zero blow by cold and...
  8. 2013-2018 Powertrain
    First time poster , long time reader. Hoping someone can help me here. I have a 2016 6.7 cummins. So far it's only deleted and tuned . It has 107 k miles on it. I did the tune and delete around 90k miles. The tunes are clean on every setting. Never smoked. A few months ago, before the weather...
  9. 3rd Gen. Powertrain
    Howdy, I have an 06 2500, 5.9, 6spd, 204k miles.The DMF was ripped out and replaced with a Valair DD a week after it was bought. I swapped injectors about a month ago because I was getting a ton of smoke, a slight miss, and it just ran like crap. I swapped the injectors and now I've got a...
  10. 98.5-02 Powertrain
    Hey guys, just joined the forum to ask about this. I've heard other 24v of the same year and they sound much quieter. Much more like a sewing machine, where as mine has an obvious knock to it. I'm assuming its injector related. If I coast down a hill or left off the throttle, the knocking...
  11. 3rd Gen. Powertrain
    I have a 2004 5.9 with 345,000 on it. When motor is not being stressed it will occasionally hesitate and the check engine light comes on. Code is for low fuel rail pressure. After the hesitation the truck performs normally and the light (check engine) goes off after a day. Fuel filter is new...

    Alright so, new injectors in 2018 at 220k, ran fine for a while then one day it shut off at 75mph. Threw a code that pointed to electrical. Ended up replacing throttle position sensor, fuel rail pressure sensor, fuel rail relief valve, male plug to TPS, injection pump, had injectors tested and...

    Hey gents, Been a while since I’ve been on here as it’s been a while since I’ve been in a cummins. back in February I bought an 03 2500 6 speed 2wd with about 140k on the clock. Truck is all stock. Always started a little slower than I’d like but nothing terrible. About a month in it Started...
  14. 94-98 Powertrain
    When pulling out and driving up a hill, or under load, my truck has a shudder that shakes the whole truck usually around 40-50mph. When I let off or get on it harder the shudder usually stops. I also found that when in park and blipping the throttle, the truck has a quick sputter of the engine...
  15. 2003 & Early 2004 Only Discussion
    Hi all, I would really appreciate some help with this issue I'm having. I am working on a 2003 Dodge 2500 with a 5.9 Cummins. 229,000 miles. Initial complaint was a really rough idle and lots of white smoke. I did a cutout test. All 6 cylinders fluctuated at idle when I cut them out...
