    2016 LML. Maybe a bad injector?

    @Bdsankey Well, my friend finally got the results back on his injectors and all 8 of his tested bad. The shop warranted all 8 of them and they ordered them through S&S diesel. I tried to get them to order from you, but the shop insisted on ordering from the company that tested them, which is...

    2016 LML. Maybe a bad injector?

    Also, as a side note. I have been driving mine and all the codes went off but injector number 2 code. The code is different now though. Its P01CE. My scanner just reads "injector 2 performance". The fuel rattle and misfire is gone too. I might just have 1 bad injector and even it is firing. No...

    2016 LML. Maybe a bad injector?

    @Bdsankey I am still waiting for the injector testing to be performed. What's going on is that a friend of mine sent all 8 of his off to be tested. He said that regardless he is going to order a new set. Some of them are under warrenty through a shop doing work on it. I gave him your name and...

    2016 LML. Maybe a bad injector?

    So, I have the truck back from the tuner. He said 2 of my injectors were bad and that the circuits tested good. He also said that he showed a vacuum loss of 3% and that anything above 1% indicated a vacuum/boost leak or bad injector seal. Below is the balance rates and some of the test info.

    2016 LML. Maybe a bad injector?

    Sorry, it was a Dorman injector, not Duralast. I also replaced the fuel line with it. Here is the injectors I have changed with new ones...injector 3 (duralast), injector 8 (duralast)...both coded at dealership. Now injector 7 (dorman) not coded yet.

    2016 LML. Maybe a bad injector?

    Well crap, I already dropped the truck off with him. I may have to go pick it up. It has a horsepower and delete tune on it. I don't know anything about software on these things. I shouldn't have done it then sounds like. He does custom tuning though....I know he put hp tunes on them. Surely he...

    2016 LML. Maybe a bad injector?

    Ok, I took the truck to a tuner that used to work for the dealership 5 years ago. He hooked a laptop up and said that injector 7 was way off and number 6 was freezing at 0.0...whatever that means. He said it was like it didn't know if it should go into open or close loop or not. He also said...

    Nate's Dmax is correct. I know him from another forum and he already knew my truck is a 2016. Sorry I didn't add that in the description. You sure know your stuff though. I sure appreciate you helping me.

    2016 LML. Maybe a bad injector?

    The only gear that I didn't check was the injection pump gear. It came pre-installed on the new injection pump. It was a gm genuine pump. Is there any possibility that the injection pump gear could have been installed without a pin? I just though about that

    It runs like a scalded ape when you floor it. It only stumbles at low rpms and idle. I am not sure that helps any

    2016 LML. Maybe a bad injector?

    Yes, it shifts fine and moves fine....I maybe should take it back apart and check the pressed on crank gear, but the oil pump drive gear/crank reluctor gear still has its pin. If the pressed on gear spun, I would probably hear valve contact and bad noises though wouldn't I?

    2016 LML. Maybe a bad injector?

    Ok, well I did replace the reluctor wheel with a used one from ebay and a new cam gear from rockauto. I had a scissor gear fail. There was no broken pins or problems like that. The crank was not broke. I had the trans dropped and removed the upper and lower oil pan. I just don't know what I...
