Low oil pressure on a gmc 1500 sierra

[travis.smith.581730]

I have a gmc sierra that oil pressure Is in between O and 40.when I press the gas it goes up to 40 and when I release it goes back in between. It feels like it has lost power. What could that be??

theres a screen under the sensor that plugs up. u need to remove the sensor clean the screen and voila fixed. very common problem. but I would recommend not driving until you check it in case there is actually no oil pressure even though the damage will have been done already,

Oil pick up tube O ring, very common problem in earlier 5.3s.
