My truck is all of a sudden pulsating while im driving..? the water temp gauge bounces between 160-185 and the headlights flicker. But the amp gauge stays the same the whole time.when it is doing it the motor makes a real loud piston knocking sound... almost sounds like an old cummins... any ideas what this could be...???

Have you pulled the Edge Juice completely out, also program it back to stock. If anything ever happens it is best to see if it is still doing it with the aftermarket stuff removed. :drink
