    Injector rates help

    Hi, I have a 2011 LML that has around 260k on it. My injector rates are something I’m questioning a little.

    Lml stuck in high idle?

    Camshaft Interchangable?

    There’s an expensive back-story, but I’m tearing down a Blackwater rebuilt LML long block with 14,000 miles that has sheared the pin that aligns the camshaft gear to the cam. Looking at the camshaft, it says LBZ 2010. Anyone know if the shafts for LML and LBZ are interchangeable?
