Oil pressure zeros out at idle 2000 Dodge Dakota 4.7
2000 dodge Dakota 4.7 motor. Drive everyday 5 miles to and from work never an issue. Today I drove about 30 miles and started hearing engine noise. When I can to a stop check gauge light came on and oil pressure has dropped to 0 and then right back up when rpms went up. Did oil change 400 miles ago 5w-30 oil mileage and fram oil filter.
