    LLY Fuel Rate Low?

    I got them from Thoroughbred Diesel, it’s their brand stock replacements. The truck was doing this before I replaced the injectors as well

    LLY Fuel Rate Low?

    Idles rough thought it was injectors so I replaced all 8 and it still does it. Rail pressure desired vs actual is within 100 psi of each other at all times.

    LLY Fuel Rate Low?

    Did you figure anything out? My 2004.5 is doing the same thing, just replaced all the injectors 2 weekends ago and the main injection rate is still low.
