Anybody have trouble with one of these? I did the master disable on the AFM, Cylinder Deactivation or DOD whichever you prefer to call it.

Here's my question. Before I get started the thing runs strange. Seems to be racking up misfires on Bank 1 cylinders 1,3 and 5 mostly. But gets some on Bank 2 also. Came in with the calculated alcohol content at 55%. Reset that and seemed to help some. But not enough. You can feel it run rough and the LTFT is going on and off. The LTFT goes as low as -10 to -12 at times but doesn't stay consistant. Will set P0300 if you let it sit and idle long enough. My gut says there is something wrong. Before I spend time trying to compensate for what seems to be a pretty small camshaft to me.
Thanks
