All of a sudden one day it was fine and next was terrible shuddering and lunging. Checked all fluids and oil was a bit low so filled to proper level. Water level was full. When I took to dealership Jeep they said I only had one pound of oil pressure and maybe it was lifters. In two week at the Jeep dealership I still do not have any answers. Engine sounded like it was starving for fuel. Had proper fuel in it and was sufficient. Terrible knocking and lunging action while driving carefully and slowly.
