So I’ve got a 99 1500 with a 5.9 360 oil pressure light came on about a month ago so I did the sensor still came on so I did the oil pump and it’s still doing the same thing having low pressure at idle and even when I’m driving it’s not as high as it should be I put a mechanical gauge to see if maybe the gauge cluster was bad and sure enough I’ve got actually low pressure last night it was 6 at hot idle and only 20 while driving idk what it could be and need some advice
