Dad was driving and started losing power, pulled over and stopped. Engine starts and idles fine. Put in gear and release clutch, it stalls. Check engine Code P0601. Had ECM rebuilt. Installed today and engine stalls , but no check engine codes. Checked wiring harness on valve cover stud and no damage there. Jeep will actually move a couple of feet now if revs are high, before it stalled immediately. Looking for any ideas
