Ok so at 1100rpm my truck, sometimes usually when it is warmed up, Will vibrate or miss, something at 1100 rpm. I thought it was drive train but I can also do this missing affect in park as well. Obviously doesnt shake like that as it doesnt have the driving force to exaggerate it. I been told everything. It is the torque converter, it is an injector, it is my pump, maybe harmonic balancer.. Here are two videos. Curious to hear what the good folks on this forum have to say. Thanks
